the whole, and accordingly the bony frame alone lies before us. The zoological 

 characters of the species, as far as we could ascertain, differ from those of each of 

 the species previously described ; but having mislaid the notes taken at the time 

 of unpacking the collection, we do not feel justified in giving a diagnosis of them 

 from recollection, and merely record the species under the above specific name.

26. Jults modestus, G. Body slender, elongated, and much compressed, 

 tapering posteriorly from the origin of anal. The greatest depth, measured upon 

 the middle of the abdomen, enters five or six times in the total length. The 

 head is subcorneal, and constitutes about the fifth of the entire length. The eye 

 is large, subcircular, and its horizontal diameter is contained four times and a 

 half in the length of side of head. The dorsal commences above the base of the 

 pectorals, being quite low for about half its length, and terminating at about 

 three quarters of an inch from the base of the caudal. The origin of the anal is 

 opposite the eleventh ray of the dorsal, and extends a little further back; the 

 depth of that fin is equal to the height of the portion of the dorsal opposite to it. 

 The eaudal is posteriorly subtruncated. The insertion of ventrals is opposite 

 the posterior extremity of base of pectorals, and their tips do not extend as far 

 back as those of the latter fins.

The scales are very large ; the fall of the lateral line takes place in advance 

 of the posterior extremity of the base of dorsal fin. 



Rufous brown above, yellowish upon the sides, and dull whitish yellow beneath. 

 Anterior seven dorsal spines with a black spot at their base ; a blackish blotch 

 at the base of the caudal.

A large specimen of this species, collected at San Diego, Cal., contained five 

 young ones, the total length of the largest beinu nearly three inches, and its 

 depth equal to the third of its length. Their bodies are light reddish orange, 

 with the peculiar longitudinal light strip?s very conspicuous. The two anterior 

 thirds of dorsals, the anterior third of anal, and the base of ventrals exhibiting a 

 deeper reddish orange ; the posterior portion of dorsal and of anal fins are rather 

 yellowish. An elongated jet black spot exists near the base of the anterior 

 portion of the soft dorsal ; the tip of ventrals is black ; the margin of the anterior 

 dorsal fin also black. 



The caudal is long and truncated ; the extremities of both the dorsal and anal 

 fins extend beyond the base of caudal as appears to be the case in the young of 

 Rhacochilns tozotes.

30. Embiotoca cassidyi, G. There is another species of Embiotoca, the young 

 of which exhibit the same structure ol the fins as observed in those of E. lineata,
