492 DEEP-SEA FISHES OF THE ATLANTIC BASIN. 



NOTES ON THE TYPE SPECIMEN. 



The type of Cryptnpsaran Gouesii, at present is only 35 millimeters long', the caudal being 

 imperfect. The length without caudal is .'50 millimeters and contains the greatest height 

 2J times. The bulb 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 about one-fourth of the 

 length without caudal. The gill opening is nearly midway between the front of the head 

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

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

 the symphysis of the mandible there is a pair of minute spines closely connected at the 

 base and slightly separated at the extremity. 



Specimen No. 39483 is 58 millimeters long; 47 millimeters to base of caudal. The 

 greatest height is contained in the length without caudal 2§ times. The gill opening is a 

 little nearer to the end of the caudal than to the front of the head. The distal portion 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 covered with minute granules of uniform size. The pectoral coutaius 16 

 lays; its length is about one-fifth the length of the head. The length of the upper jaw is 

 about one-fifth of the total without caudal. The pair of spines at the symphysis of the 

 mandible is replaced by a Aery small knob. The teeth in the intermaxillary are all very 

 small, diminishing in number 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 of Mancalias Sh ufeldtii, 

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

 Greenland before 1871.
