Body elongate, soft, and translucent. Head very short; mouth small, 

 toothless. Eyes sinistral, close together, the lower slightly advanced. 

 Pectoral of blind side smallest; ventrals crowded together on median 

 keel of body, their bases prolonged on this keel. Eays simple ; dorsal 

 beginning on the snout; caudal subsessile, almost confluent with dorsal 

 and anal. Scales very thin, easily detached, probably cycloid. Lateral 

 line well marked, straight, (/novo^, one; (bXevrf, arm.) 



a. Dorsal rays 99 to 103 ; anal rays 79 to 81 ; scales 92. SESSILICAUDA, 3063. 



aa. Dorsal rays 124; anal rays 100; scales 105. ATRIMANA, 3064. 



3063. MONOLENE SESSILICAUDA, Goode. 



Head 5 in body; depth 2f. D. 99 to 103; A. 79 to 84; scales 23-92-25; 

 eye 4 in head; highest dorsal ray 2; highest anal rays slightly more than 

 3; pectoral 1^-; caudal nearly 1. Body moderately elongate ; maxillary 

 extending slightly past front of lower eye, with uniserial, subequal teeth ; 

 lower eye in advance of upper ; interorbital space very small, less than ^ the 

 diameter of eye; head every where closely scaled; scales ctenoid; lateral 

 line strongly curved over anterior f of pectoral, the curve with 2 angles, 72 

 scales along straight portion; lateral line of blind side nearly straight. 

 Origin of dorsal over anterior edge of lower eye, longest rays in the poster- 

 ior fourth of the fin; origin of anal under base of pectoral; pectoral pres- 

 ent only on eyed side. Color on left side ashy brown, with numerous more 

 or less distinct darker brown spots ; on blind side white, pectoral blackish 

 with traces of lighter transverse bands. Specimens from shallow water 

 near Key West (Coll. Prof. C. C. Nutting), according^ to Mr. Garman, are 

 much more brightly colored. These are " grayish brown, with numerous 

 spots of darker to blackish over head and body, the spots being -J as large 

 as the eye or smaller, arranged for the greater part in broad transverse 

 bands as wide as the interspaces, of which bands the first and foremost 

 passes from the nape to the opercle, the second lies immediately behind 

 the pectoral, the third just in front, and the fourth just behind the middle 

 of total length, and the fifth, more indistinct, crosses near the ends of the 

 dorsal and anal; the caudal is crossed by 2 rather indefinite narrow 

 streaks ; the pectoral is white at its base and bears 3 or 4 narrow curved 

 transverse bands of white, separating 3 or 4 similar bands of black, 

 which with the white are more distinct in the lower half of the fin." Spec- 

 imens from 150 fathoms or more have markings similar but less distinct. 

 D. 104; A. 84; V. 6; P. 11; scales 22-93-24. Deep waters of the Gulf 

 Stream, Cape Cod to Key West, (sessilis, sessile; cauda, tail.)
