Syngnathus auliscus (Swain) 

 Collected with S. leptorhynciis at Anaheim Landing. The color 

 is plain brown, sometimes with lighter rings. The specimens show 

 the same differences from current descriptions that were noted by 

 Starks and Morris.'^ Two specimens collected in San Diego Bay on 

 February 14, 1914, are 100 mm. long, one a male with eggs in the 

 pouch, the other a female with mature ova. 



Syngnathus arctus (Jenkins and Evermann) 

 Two specimens were taken with S. leptorhyncus in the eel-grass of 

 Spanish Bight, San Diego Bay, by Mrs. Frank Stephens. 



Leuresthes tenuis (Ayres) 



Specimens were bought from a fisherman, who had seined them 

 between Newport and Laguna. Dorsal IV or V-I, 8 to 11. 



Several specimens of this species were sent to Stanford University 

 by Mr. J. B. Joplin, of Santa Ana, who described the breeding habits 

 of this fish. He wrote : 



"It is the peculiar nature of these fish which attracts our attention. 

 Three months during the year, usually March, April and May, on 

 the second, third and fourth nights after the full moon, at full tide, 

 great schools of them come out in the breakers, at the mouth and for 

 half a mile on each side of where a small fresh water stream flows 

 into the ocean, for the purpose of depositing its eggs or spawn in the 

 sand. The water recedes and when the fish are not disturbed they 

 wiggle tails down in the sand, as far out as the force of the water 

 will carry them, both males and females together— sometimes as many
