not utilized. Some are caught with grab hooks off the wharves. and are 
sold at 5 cents perdozen. They reach a length of 0.30 m.; but few speci- 
mens of such size are caught. At times they are in such abundance 
that bushels of them are left at low tide in the small puddles about 
piles. . 
Young ones remain in the bay during the summer. 
The spawning season has not been ascertained.

The members of this family are probably found here throughout the 
_ year, but they are certainly much more abundant in spring and sum- 
ri mer than in winter (if they are herein winter at all). During spring and 
— summer they furnish a large pei cent of the food of all the larger fishes. 
_ The species inhabiting San Diego waters may be distinguished by the 
following key: 
a. Spindle-shaped, form of Clupea sagax, no silvery lateral band, bluish above, not 
translucent. A. 22; Head 3}. Ovaoval. Young more compressed, sides silvery 
but without well-defined band, not translucent....--....-..-.-...-.-. ringens. 
aa. Strongly compressed, a silvery lateral band, translucent in life. Head 4}. .

_ The pelagic eggs of these species are the most striking feature of the 
surface fauna in April, May, and June. The oval eggs were first 
~ obtained on April 18, and on account of their bizarre appearance were 
at first set aside as not fish eggs, but the gastrulation soon convinced 
me that they were. They are so abundant during May that quantities 
-- have been obtained simply by several times throwing the skimming net 
— over the water and drawing it in while standing on the float of a boat- 
house. The oval eggs of delicatissimus, ringens were the first to appear, 
the round eggs of compressus appear later. The yolk is collected in clear 
transparent spheres.

This is the largest anchovy found at San Diego. It is found in the 
bay m summer and ranges from the surface to a depth of about 100 
fathoms in the ocean off Point Loma. It is found in the stomachs of
