in 2 series, merging into 1 laterally, the outer series anteriorly somewhat 

 enlarged; teeth in front ofmandibk^ in a broad band, narrowing laterally 

 to a single series, none of them enlarged; vomer and palatines with single 

 series. Head with 2 series of large and very conspieuons elongate pores, 

 1 series on mandible and suboperele, the second parallel with it on level 

 of snout. Gill openings wide, extending forward beyond preopereular 

 margin, the width of isthmus less than \ length of slit. Distance from 

 origin of dorsal to tip of snout ^\ in length. Median dorsal rays simply 

 forked near base, those posteriorly in both dorsal and anal repeatedly 

 subdividing. Distance of anal from snout 2f in length; pectorals 

 rounded, the lower half of fin longer than the upper, the rays thickened, 

 the fin containing 15 or 16 rays, its length less than \ head; veutrals 

 longer and slenderer than usual, each apparently composed of 2 rays 

 closely joined, their length f orbit, inserted unusually far forward, 

 being in advance of preopercular margin. Scales very small, circular, 

 partially embedded, covering body and vei'tical fins; head, antcdorsal 

 region, breast, and a strip connecting the two latter embracing base and 

 axil of pectorals, naked; lateral line median. CUdor dusky brown, the 

 fins, sides of head, and belly blackish ; lining of mouth and gill cavity 

 and peritoneum black. Oft' Lower California. A single specimen, 12 

 inches long, from Albatross Station 3009, in 857 fathoms. A transitional 

 species approaching Furcella. {porus, pore; fei-o, I bear.)

938. FURCIMANUS, Jordan & Evermann. 



Furcimanus, new geuus (diapterus) ; Jordan & Evermann, Check-List Fishes, 480, 1896 

 (diapterus) ; preocciii)ied by Furcelhi, Laroiirck, 1801, a genus of molliisca. 



This genus dift'ers from Lycerichelys in the forked pectorals, the upper 

 and lower rays being much longer than the middle ones. The latera 1 line 

 is single and V(>ntral in position (not lateral as in Lyceuchclys). (furca, a 

 fork; manus, hand.) 



2835. FURCIMANUS DIAPTEUA (Gilbert). 



Head 5| to 6; depth 12; eye large, usually longer than snout, 3 to 3j in 

 head; snout 3^ to 3|; interorbital width about 10. Body slender. Mouth 

 small, somewhat variable in length, the maxillary reaching vertical from 

 between front and middle of pupil, 2| to 3 in head. Teeth in i)remaxillaries 

 in a double row throughout, the 2 series well separated, rarely with 1 or 2 

 teeth intercalated, showing traces of a third row; the teeth of inner series 

 small and directed obliquely inward; those of outer series anteriorly 

 enlarged, becoming smaller on sides of jaw ; on front of mandible the teeth 

 are in a broad band, in which traces of 3 or 4 irregular series can be made 

 out ; none of these enlarged ; laterally the teeth are arranged in a single 

 series, those opposite middle of cleft considerably enlarged ; a small patch 

 of from 2 to 5 teeth on vomer; palatines with a single row much shorter 

 than premaxillary patch. Nostril with a. short inconspicuous tube. Man- 

 dible and preopercular border with deep pit-like excavations, w^hich arc 

 not evident in fresh specimens; no evident mucous pores on the head.
