DISCUSSION OF SPECIES AND THEIB DISTRIBUTION. 491 



limes iii ili is length. This form is more Blender than thai figured by Giinther, and 1ms five 

 rays in the dorsal, and apparently fifteen in the pectoral. 



There are no vomerine*. The intermaxillary and mandible arc armed with a narrow 

 baud of depressible teetb of various lengths. The skin has a fine granular appearance 

 and is every where covered with minute prickles. The median dermal caruncle referred to 

 in the description of this species has been torn off. The caruncles are only 2 in number 

 and situated as in M~ancalia& uranoscopus, as figured in the Challenger Fishes. The length 

 of the dorsal spine, without the joint bearing the pear shaped appendage, equals the dis- 

 tance from the gill opening to the root of the tail; the joint bearing the appendage is 

 two fifths of this distance. The length of the specimen at. present is about 2:; inches. In 

 Mancalias uranoscopus (26159) the first dorsal, without the joint bearing the appendage, 

 contains the distance from the i;ill opening to the, root of the tail 1 j times. The joint con- 

 taining the appendage is one-halt as long as the distance from the gill opening to the root 

 of the tail. The dermal caruncles are distant, from the dorsal a, space, equal to one-si\th of 

 the distance from the gill opening to the root of t he tail. In Typhlopsaras Skufeldtii the 

 caruncles are placed at a distance from the dorsal a space contained 4£ times in the dis- 

 tance from t he gill opening to the, root of the tail. 



In the specimens described by Uoode and Hennas Mniiciiliiis unoioscopus (No. 26159), 

 the length '■>] inches, the length of the maxilla is one-third the length from the gill opening 

 to the rooi of I he tail, and the intermaxilla, 34 times in the same distance. The teeth in the 

 jaws are depressible, in narrow bands, and of unequal size. The vomer is toothless. 



There are two small caruncles not far from the front of the dorsal tin, and instead of 

 being placed opposite each other, according to the usual arrangement, one is placed 

 behind the other. The skin is covered with minute granules or papilla-, each one sur- 

 mounted by a slender prickle, as in Typhlopsaras. 



The pectoral of this individual contains 15 rays. The pectorals of T. Shufeldtii are 

 imperfect. 



In the note published by Dr. Goode in Proceedings U. S. Nat. Mus., vol. in, L881, 

 469, the length of this specimen is stated to be 185 millimeters, which is a misprint for 85 

 millimeters. 



CRYPTOPSARAS, Gill. 

 Cryptopsaras, Gill, Forest and Stream, Nov, 8, 1883, 284. 



Oeratiines with shortened trunk, longitudinally convea back, small but conspicuous 

 eyes, concealed basal joint of the anterior spine and elongated terminal joint, a large inter- 

 mediate globular, and a pair of subpedunculated lateral dorsal appendages near the front 

 of the dorsal tin, and well developed pectorals of about 15 rays. [Gill.) 



Giinther's Geratias carunculatus was obtained by the Challenger from a depth of 345 

 fathoms, at station 232, south of Yeddo, in Japan, the single specimen being 14 inches 

 long.

The basal joint of the rodlike spine is almost entirely concealed and procumbent, and 

 I In- distal joint alone lice, reaching backward to the dorsal tubercle; the bulb is pyriform, 

 and surmounted by a long whitish filament; the dorsal and anal have each 4 spines, the 

 caudal 8 (the 4 middle dichotomous), and the pectorals each about 15 rays. The species 

 was named after the eminent ornithologist Dr. Elliott (Jones. (Gill.) 



A specimen of Cryptopsaras (Cat. No. 33558, 0". S. Nat. Mus.) was obtained, by the 

 Albatross, from station 2101, in 38° 18' 30" N. hit,, 68° 21' \Y. Ion., at a depth of 1686 

 fathoms.
