Of three adtilts of S. leptorhynchus collected in El Estero, 

 near Carpenteria, Santa Barbara County, on July 4, two were 

 males, one containing eggs in its brood pouch, the other well- 

 developed embr}'OS. 



Synynathus leptorhynchus appears to be the southern rep- 

 resentative of S. griseo-lineatus, differing from that form in 

 having fewer dorsal rays and fewer caudal rings. There is 

 apparently no basis for records of leptorhynchus north of 

 Point Conception.

The characters of this species, like those of the other forms 

 inhabiting the California coast, are subject to considerable 

 variation. The following table of measurements and counts 

 is based on specimens from the entire known range of the 

 species.
