3rd joint with spine in row on medial surface (not shown) and 2 bristles (1 dorsal with short spines, 1 ventral bar). 9th joint with 2 bristles (ventral long with ventral spines (Figure 9j)\ dorsal short with few slender spines). 3rd endopodial joint with 2 strong terminal claws (with ventral spines) and 2 ringed bristles (1 ventral, 1 dorsal).
3rd endopodial joint with 3 spinose claws (dorsal claw about xh length of longest claw) and 3 hairs. 2nd endopodial joint with 3 hairs A with thin rings, 2 hairs b, 1 hair with short rings and 3 punctures d similar to those of adult female. 2nd endopodial joint with 3 or 4 hairs A with fine rings, 2 hairs b and 3 hairs d similar to those of adult female and 2 fine ring hairs.
Second endopodial joint with 4 fine ring hairs a, 2 b hairs and 3 d hairs similar to those of adult female and 3 fine ring hairs. Second antenna: Endopodite: first joint with 5 instead of 6 hairs; otherwise similar to that of the adult female. 6th joint with 1 long medial hair with small indistinct spines (spines not shown in figure \0h).
Exopodite: 1st joint with 9 setae (1 very long distal dorsal seta with widely separated marginal spines, 2 transparent plumose setae on or near dorsal margin at mid-joint, 1 proximally near ventral margin or near mid-joint, 1 proximally on ventral margin, and 4 distally near the ventral margin). 3rd exopodial joint with 3 setae of equal length (2 dorsal claws (weakly ringed distally), 1 ventral thin ringed). Exopodite: 1st joint with 6 setae (3 ventral, 3 set from ventral margin, none dorsal); 2nd joint with 3 setae (1 ventral, 2 dorsal); 3rd joint with 3 ring-shaped glabrous setae (middle slightly longer).
A difference from previously described species where the character is known to be more spiny and to have long proximal hairs on the shorter claw (Figure 22c). The claws of different species of Bathyconchoecia in the collection of this museum are compared in Figure 23.

DISTRIBUTION. - Guaymas Basin (southern trough), Alvin dive 1629, bottom depth 2000 m, collected in plankton 3 to 4 m above the bottom. Endopodite (Figure 25e,f): 1st joint with 2 dorsal a- and b-bristles spinous processes (a-bristles about 74 lengths of b-bristles); 2nd joint with 2 minute unringed c and d bristles (Figure 25/) and 2 long f and g bristles; 3rd joint with base medial to 2nd joint, and point with sclerotized border (joint of right limb with small terminal node), with h, i, and j bristles. Endopodite separated from endite II by a minute notch in the ventral margin, with 2 short, stout, unringed, indistinctly spiny tooth-like setae and 3 slender spiny setae.
Exopodite: 1st joint with 7 hairs near ventral margin, 2 diaphanous plumose hairs near dorsal margin, and 1 very long spiny hair on dorsal margin; 2nd joint with 3 hairs on ventral margin and 2 on dorsal margin;. 3rd joint with 2 claw-like dorsal hairs and 1 thin ringed ventral hair (middle brush the longest). Exopodite: 1st joint with 4 hairs on or near ventral margin; 2nd joint with 2 hairs (1 ventral, . 1 dorsal); 3rd joint with 3 ringed bristles.
Furca (Figure 25/): Each limb with 7 claws with double row of teeth along posterior margin; claw 1 with 3 proximal weakly developed sutures; 1 unpaired long spinous bristle on lamellae after claws; lamellae hirsute. Arranged north to south and in chronological order of specimens for each locality; number immediately after the name of the underwater vessel is the diver's number). The number of bristles on the adult ninth exopodial joint of the second antenna of selected species of Philomedidae.
Number of Bristles on the Adult Ninth Exopodial Joint of the Second Antenna of Selected Species of the Philomedidae
I re-examined the specimen and found that each limb has 9 exopodial joints, with the left limb having 4 setae at the 9th joint and the 9th joint of the right limb obscured but with at least 3 setae, possibly 4.

Requests for special treatment—use of color, folds, box-bound covers, etc.—require, on the same form, the added approval of the sponsoring authority. Press review of manuscripts and art for requirements of serial format and style, completeness and clarity of copy, and arrangement of all material, as outlined below, will, within the judgment of the Press, govern acceptance or rejection of manuscripts and art.
On the first page of the text, the title and author should be at the top of the page; the second page should contain only the author's name and work mailing address, which are used as an unnumbered footnote on the first page of the printed text. Synonymy in zoology should use the short form (taxon, author, year: page), with full citation at the end of the paper under. Extensive notes should be collected together and placed at the end of the text in the notes section.
For titles of books and articles, use capital letters in sentence form, according to the rules of the language used (exception: capitalize all important words in English). Legends for illustrations should be submitted at the end of the manuscript, with as many legends typed, double-spaced, on a page as is convenient. The use of the metric system of measurement is preferred; where use of the English system is unavoidable, indicate metric equivalents in brackets.
