21, CENTBONOTITS. 287 



represents a fish perfectly identical with the European, even with 

 regard to the depth of the body, which, in the specimen figured, is 

 nearly one-ninth of the total. 



Skeleton. — The skuU is compressed and rather short ; its crown 

 rounded on the sides and perfectly smooth ; the interorbital space 

 very narrow ; infraorbital ring rudimentary. The vertebrae are com- 

 pressed, short, higher than long ; the lower processes of all the 

 abdominal vertebrae are united and form a haemal canal.

The height of the body is eight times to ten times and a half 

 in the total length, the length of the head ten times and a half. 

 Snout short, with the cleft of the mouth very oblique. The width 

 of the interorbital space is less than the diameter of the eye. The 

 length of the pectoral is equal to, or rather less than, one-half the 

 length of the head ; ventral very small, composed of one spine and 

 one ray ; dorsal spines very short and stiff; caudal distinct. Greyish- 

 or brownish-grey, marbled with darker, anteriorly with several rather 

 irregular cross-bands, descending to the abdomen ; back with a series 

 of ten or twelve subtriangular light-coloured spots along the base of 

 the dorsal, each spot including some brown specks. A yellowish or 

 whitish, brown-edged vertical band behind the eye ; a brownish band 

 from below the eye to the throat.

 of the mouth oblique. The width of the interorbital space is rather 

 less than the diameter of the eye. The length of the pectoral is 

 nearly one-half of that of the head ; ventral very small, composed of
