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

 enlarged; teeth in front of mandible 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 conspicuous elongate pores, 

 1 series on mandible and subopercle, the second parallel with it 011 level 

 of snout. Gill openings wide, extending forward beyond preopercular 

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

 origin of dorsal to tip of snout 4 in length. Median dorsal rays simply 

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

 subdividing. Distance of anal from snout 2| 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; ventrals 

 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 vertical fins; head, antedorsal 

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

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

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

 and peritoneum black. Off Lower California. A single specimen, 12 

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

 species approaching Furcella. (porus, pore; fero, I bear.) 



Lycodes porifer, GILBERT, Proc. TJ. S. Nat. Mus. 1890, 104, off Lower California, in 857 fath- 

 oms. (Type, No. 44384. Coll. Dr. Gilbert.) 



938. FURCIMANUS, Jordan & Evermann. 



Furcimanus, new genus (diapterus) ; JORDAN & EVERMANN, Check-List Fishes, 480, 1896 

 (diapterus) ; preoccupied by Furcella, Lamarck, 1801, a genus of mollusca. 



This genus differs from Lycenchelys in the forked pectorals, the upper 

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

 is single and ventral in position (not lateral as in Lycenchelys). (furca, a 

 fork; manus, hand.) 



2835. FURCIMANUS D1APTERA (Gilbert). 



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

 head; snout 3 to 3f; 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 premaxillaries 

 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, which arc 

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