The Sea-cat attains a considerable size. Its length 

 is usually between 4 and 7 dui., but specimens 12 dm. 

 long are occasionally found. The body is elongated 

 and more or less cylindrical; the sides strongly com- 

 pressed, especially in the caudal region, and the belly 



pendent. The greatest deptli of tlie body shows even 

 relative increase with age: in specimens from 100 to 

 400 mm. long it measures nearly 18 % of the length, 

 and in specimens 11 dm. long about 22 %. The head 

 is comparatively small: during early growth, from a 

 length of 100 to about (jOO mm., its length sinks from 

 23 to about 20V2 % of that of the body; but sub- 

 sequently seems, even relatively, to increase, being 

 about 22 % of the length of the body in specimens 

 11 dm. long. The top of the head is rounded, the 

 sides compressed, and the temples and cheeks tumid, 

 thus showing the strength of the masticatory muscles. 

 The snout is short and blunt, and the jaws project 

 about equally. This circumstance, in conjunction with 

 the long, conical front-teeth, gives the head a certain 

 resemblance to that of a cat, and hence is derived the 

 name of the species. The eyes are of moderate size 

 and set high, close to the upper margin of the fore- 

 head, and nearer to the snout than to the occiput. In 

 specimens about 100 mm. long the diameter of the eye 

 is about '/g of the length of the head, and twice the 

 least depth of the tail; in specimens about 400 mm. 

 long about equal to the latter; and in specimens 11 

 dm. long the diameter of the eye is only slightly more 

 than half the least depth of the tail. Thus, the changes 



" SoiMCluiies 09 or even as luaiiy as 77, according to NiLSSON. 

 ' Generally from 43 to 46, according to Lilljebobg. 

 ' Sometimes 21, according to Bean.
