492 DEEP-SEA FISHES OF THE ATLANTIC BASIN. 



NOTES ON TUE TYPE SPECIMEN. 



The type of Crypioitsnrax CloiiesU, ;\t present is only ."..") millimeters long, the caiulal beinj;: 

 imperfect. The lengtli without canclal is .'$0 millimeters iuid contains tlie greatest height 

 '2i times. The bnlb on the dorsal spine when laid backward can be made to reach the 

 dermal caruncles on the back. The length of the upper jaw is abont one-fonrth of the 

 length without caudal. The gill oi>ening is nearly midway between the front of the head 

 and the root of the tail. The moutli is placed vertically. The intermaxillary teeth occupy 

 about the entire length of the bone. The mandibulary teeth are very unequal in size. At 

 the symphysis of the mandible there is a i)air of minute spines closely connected at tlie 

 base and slightly separated at the extrenuty. 



Specimen No. 39483 is n.S millimeters long; 47 millimeters to base of caudal. The 

 greatest height is contained iu the length without cauihd 2'r; times. The gill opening is a 

 little nearer to the end of the candal than to the front of the head. The distal jiortion of 

 the dorsal spine is about one-half the length without caudal. The median dermal caruncle 

 is very much larger than the two lateral ones. 



The skin is (;overed with minute granules of uniform size. The pectoral contains 16 

 rays; its length is about- onelifth tlie length of the head. The length of the upper jaw is 

 about one-fifth of the total without caudal. The i>air of spines at the symphysis of the 

 mandible is replaced by a very small knob. Tlie teetli in tlie intermaxillary are all very 

 small, diminishing in nnnd)er towards the symphysis; they are apparently uuiserial. 



On each side of the head of the vomer there are two or three depressible teeth ; the 

 palatines seem to be wanting. 



We have seen something like traces of similar teeth on the vomer otMancalias SlnifeldtU, 

 but owing to the condition of the specimen can not be certain about this character.

 Greenland before 1871.
