Mr. Charles H. Townsend from a rock pool at San Cristobal, Lower 

 California, 500 miles southward from San Diego, Cal. 



There seems to be no doubt that these specimens belong to the spe- 

 cies called by Jordan & Gilbert Salarias ailanticus. It is, however, yet 

 to be compared with Atlantic examples. 



The specimens have been sent to the United States National Mu- 

 seum. 



Bupiscartes atlanticus was accompanied by the young of Girella nigri- 

 eans and Pomacentrus ruMcundus, and by Oligocottus analis, Gobiesox 

 rhessodon, Cremnohates integripinnis^ and Zabrosomus xanti. Two speci- 

 mens of the last were secured by Mr. Townsend. The larger of these 

 is nearly 2J inches in total length and agrees with Jordan & Gilbert's 

 description of Clinus nuchipinnis, except in the one character, which, 

 according to Jordan & Gilbert, is the only feature separating xanti 

 from nucJiipinnis, namely, in having three large bluntish teeth on the 

 vomer in the form of a triangle. 



" This species [xanti] is extremely close to the Clinus nuchipinnis, 

 differing, in the specimens examined, in the arrangement of the teeth 

 on the vomer. In xanti there are three large bluntish teeth forming a 

 triangle ; nuchipinnis one large tooth and about six smaller ones form- 

 ing a V-shaped figure. In nuchipinnis there is always a distinct black 

 blotch on the opercle, which is faint or obsolete in xanti. In form, 

 structure of fins, numbers of scales, &c., we are unable to find any dif- 

 ferences." {Jordan & Gilbert.) 



Now, the other example from San Cristobal is only a little more than 1^ 

 inches long and Tias six or seven small teeth on the vomer, which are pointed 

 though somewhat blunt. The markings on both specimens are well 

 defined, excepting the "black blotch on the opercle," which is wanting 

 on the smaller example. The lateral ''vertical bands" extend upon the 

 dorsal fin to its margin, anteriorly, and on the base of that fin posteri- 

 orly. The anal has eight squarish dark vertical bars, alternating with 

 lighter of similar form and size, some of the anal bars being continu- 

 ous with those of the sides. 



These specimens of Labrosomus have been sent to the United States 

 National Museum.
