750. TALISMANIA jEQTJATORIS, Goode & Bean. 



Head 2fc ; depth 3f ; snout 3f ; eye 4f, Ifc in snout. D. 22 ; A. 21 ; B. 52 ; 

 V. 7 ; P. 8 ; scales 45 to 48. Maxillary reaching vertical from posterior 

 margin of orbit. Bones of head thin ; head large, compressed, the depth 

 at the occiput f its length, its width about \ ; its upper surface longi- 

 tudinal, concave, and deeply concave between the orbits, with a convex- 

 ity above the snout ; width of interorbital space about equal to diam- 

 eter of eye ; infraorbital ring very narrow ; maxillary broad, large, con- 

 spicuously dilated at the extremity, its greatest width at this point being 

 more than diameter of eye. Cleft of mouth wide ; dentition feeble ; 

 no traces of teeth upon either vomer or palatine (on typical specimen). 

 Branchiostegals long and slender ; gills 4 ; gill laminae short, especially 

 on the convex portion of the arches ; gill rakers long, strong, broad at 

 the base ; 6 -f- 17 on the outer arch. Vent placed equidistant from root 

 of caudal and root of pectoral ; origin of dorsal over vent, slightly in 

 advance of anal ; dorsal fin longer than high, its anterior rays increas- 

 ing in length to the middle of the fin, the longest ray 3f in head, about 

 equal to longest ray of anal ; caudal fin deeply emarginate ; pectoral 

 inserted far below middle of body; it has a narrow base, and its length 

 in a perfect specimen is probably not greater than diameter of eye. 

 Ventrals close together, remote from the vent, the root being nearly mid- 

 way between the root of the caudal and the tip of the snout, and equi- 

 distant from root of anal and base of pectoral. Scales deciduous, cycloid, 

 the lateral line beginning from a point on a level with the top of the eye, 

 and ascending in a broad curve to a point over the ventrals, thence in 

 a straight line to root of caudal. Color bluish-black. A single speci- 

 men, 14- inches in length, obtained by the Albatross, from station 2793, 

 latitude 1 03' N., longitude 80 15' W., in 741 fathoms. (Goode & Bean.) 

 (cequatoris, of the equator.) 



Talismania sequatoris, GOODE & BEAN, Oceanic Ichthyology, 44, fig. 50, 1895, off coast of 

 Ecuador. (Type, No. 44085.) 



228. CONOCARA, Goode & Bean. 



Conocara, GOODE & BEAN, Oceanic Ichthyology, 39, 1895, (macdonaldi). 



Body elongate, compressed; in the type species strongly suggestive of 

 the Barracuda (SpJiyrcbna) . Mouth moderate; snout prolonged; jaws 

 strong and powerful, the lower slightly included ; teeth in the jaws 

 acicular, rather numerous; also on the vomer, very small; absent from 

 palatines. Eye large. Gill membranes entirely separate. Dorsal 

 moderate in length ; anal very elongate, nearly twice as long as the 

 dorsal; pectoral and ventral small; caudal strongly forked. Scales 

 minute and deciduous. Branchiostegals 6, the membrane of the left 

 series folded conspicuously over the origin of that of the right. Oper- 

 cular bones thin. Gill rakers rather short and stout, moderate in num- 

 ber. Deep sea. (KUVOS, cone; /cdpa, head.) 



a. Body moderately elongate, the depth 5% in length. D. 18; A. 36. MACDONALDI, 751. 



oa. Body very elongate, the depth 8 in length. D. 21; A. 40. MACBOPTEBA, 572.
