76 BULLETIN OF THE BUREAU OF FISHERIES. 



The young individual here reported on is much more slender than the type; the depth contained 

 3.6 (instead of 2.5) in the length without caudal. The dorsal contains 53 rays, the anal 44 rays, and the 

 pectoral 37 rays. Teeth are apparently arranged in but 7 oblique rows. Disk moderate, its diameter 

 about one-third length of head, its distance from tip of lower jaw two-sevenths length of head. Snout 

 with a shallow open median groove with vertical sides and horizontal floor; no thin median ridge within 

 the groove, as in the type. Pupil minute, elliptical, with horizontal axis. The dorsal fin is much 

 more widely joined to caudal, attached to the basal half of the fin, while the anal is a trifle more widely 

 joined. 



In spirits, colored much as C. cyclospilus, but the spots smaller, less conspicuous, and those along 

 base of anal are elongate, and obliquely placed. In life, light translucent olive-gray, slightly flushed 

 with reddish; the spots are red rings of various shape surrounding areas of the ground color. 



The species differs from C. cyclospilus in the presence of the rostral groove, in the long conical 

 overhanging snout, the large size of the pores on snout and mandible, the color, and in many minor 

 characters. 



The principal character on which the genus Crysiallichtkys was founded, the single nostril, is shared 

 also with Careproctus, with which its two species, mirabilis and cyclospilus, are most closely allied. The 

 genus may be provisionally retained, distinguished by the compressed head and body, the inferior 

 mouth overlapped by the conical snout, the highly translucent gelatinous texture, and the peculiar 

 style of coloration.

 6.5; interocular width 10.5; disk 5.2; distance disk to tip of mandible 15; to vent 4; to front of anal 16. 

 Dorsal 53; anal 46; pectoral 37; caudal 9. 



Head large, flat above the eyes, cuboid, its width equaling the depth just behind eyes; occiput 

 swollen; snout blunt, slightly overlapping the mouth. Mouth small; the lower jaw included; maxillary 

 reaching vertical from just behind front of pupil; teeth tricuspid, in bands in each jaw; about 10 oblique 

 series in each half of the upper jaw, 12 in the lower; eye large, shorter than snout; pupil large, round; 

 nostril single, in a short tube. Disk small, about 0.75 eye, situated just in front of vertical from gill 

 slit. Gill opening extending down in front of upper two pectoral rays. Vent under origin of dorsal. 



Dorsal beginning over tip of opercular flap; distance from tip of snout to origin of dorsal 3.33 in 

 length of body. Origin of anal fin under seventh dorsal ray. Dorsal connected with the caudal for 0.5 

 the length of the caudal; anal connected with the caudal for 0.4 its length; caudal 2.33 in head. 

 Pectoral 1.66 in head; the upper lobe composed of 32 rays, the lower lobe of 5 rays; upper rays of lower 

 lobe reaching beyond vent. 



One or two distinct pores near origin of lateral line; no further evidence of tube or pores. 



Color in life: Uniform light rose, the cotype a little dusky posteriorly. 



Besides the types a single cotype was taken at station 4771 on Bowers Bank, Bering Sea; depth 

 426 fathoms.
