NOTES ON A COIiT.ECTlOIV OF FISHES FKO.TI SAN DIEGO, VH L- 



IFORNIA. 



By DAVID S. JOIIDAIV aoid CHARLES H. GILBERT. 



The writers have spent the greater part of the month of January, 

 1880, in the collection and stndy of fishes at San Diego, Cal., in the inter- 

 ests of the United States Fish Commission. As some of the species 

 obtained are new to science, and others new to the United States fauna, 

 it is thought advisable to present an annotated list in advance of the 

 j)ublication of a more extended report. 



HIPPOCAMPID^. 



1. Hippocampus ingens Girard. 



One large specimiea seen. 



SYNGNATHID^. 



2. Syngnathus leptorhynchus Girard. 



{Syngnathus arundinaceua Girard.) 

 Kot uncommon. 



PLEURONECTID^, 



3. Paralichthys maculosus Girard. 



Very abundant. There seems to us no doubt of the correctness of 

 Lockington's identification of the '■'■TJiropsetta Galifornica'" with this spe- 

 cies. The caudal fin in the adult is somewhat double concave; iu the 

 yoiing the middle rays are more produced. This species is both dextral 

 and sinistral. Out of twenty-six examples examined in reference to this 

 point fifteen were found to be sinistral and eleven dextral. 



4. Citharichthys sordidus (Girard) Giintlier. 

 Not common ; one specimen seen. 



5. Hypsopsetta guttulata (Girard) Gill. 

 Common. 



SOLEID^. 



6. Aphoristia atricauda sp. nov. 



Body oblong-lanceolate, anteriorly somewhat blunt, regularly nar- 

 rowed behind and ending in a point, the snout rather abruptly truncate, 

 eyes and color on the left side. Eyes A^ery small, nearly even behind, 

 the ui>per eye the larger and extending farthest forward. A single nos- 

 tril in front of the interorbital space and apparently a single smaller 

 one below it. Mouth moderate, extending to opposite the eye, somewhat
