ADDITIONS TO THE FAUNA OF SAN DIEGO, WITH NOTES ON 

 SOME RARE SPECIES. 



Sphyrna ZYGAENA (L.) 



Myctophum — Sp. A single specimen from the Cortez Banks 

 which was reterred to M. townsendi differs from that species in 

 some respects. The occiput is more elevated, the preopercular 

 margin is less inclined, agreeing with M. californiense. As far as 

 evident, the sphosphorescent organs agree with those of town- 

 sendi; there is, however, no light area along the base oi the anal. 

 D. 13. A. 15. A single specimen of this species was taken out 

 of the mouth of a Rock Cod caught a few miles off" Point Loma. 



Menidia TENUIS (Ayres) — This species has not been ob- 

 served by us during the past year before Sept. nth, when a 

 large number were brought into the market. All the specimens 

 examined by us have distinct bands of teeth and if the alleged 

 absence of teeth in this species is the only character, as stated by 

 Jordan and Gilbert., Syn., N. A. Fishes, 405, separating this 

 species generally from Menidia, it must be placed in that genus. 



EcHENEis remora L. — Found on every specimen of 

 Sphyrna zygaena. 



Xenistius californiensis (Steindachner) — Raspers. 



This species has so far been very rarely found. Steindachner 

 found it in San Diego Bay, (Ichthyol. Beitr. III. 3. 1875) and 

 Streets at Cerros Island, (Bull U. S. Nat Mus., VII. 49), since then 

 the species has been noted but once, having been collected by 

 Rosa Smith in '85. The specimens collected by her are now in 

 the Museum of the Indiana University. On May 3d, '89 we 

 procured a single specimen; the latter part of August and during 

 September of this year they were very abundant about the 

 wharfs in San Diego Bay, as many as twenty being caught in a 

 day by a single person with hook and line. When they are 

 pulled from the water they grate their pharyngeals together pro- 

 ducing a noise like that ot a rasp. Silvery below, steel blue 

 above, lateral stripes rust color. ,
