Position op Young in Gravid Examples op Cymatogaster aggregatus. 



Color of fomale in life, silvery; back olive-greenish or brassy; side with 2 broad vertical brassy 

 bat's, between which and in front and back of which the scales are whitish, and with a large lilack blotch 

 of small specks; top of head olive; l)elly white; dorsal and caudal olive, other fins white. 



■' Surf-firfi " is a very appropriate name for this little species. During the spawning season it swarms 

 in great numl.iers in the surf or in shallow water along sandy shores. Every haul of the seine at Kilisut 

 Harljor and al)out Nanaimo and Fort Rupert resulted in the capture of great numljers. 



The spawning season on the coast from Puget Sound to Fort Rupert is evidently din'ing the last 

 days of June and the first days of July, and the fish seem to come into shallow water along the shore to 

 liberate their young. There is evidence indicating that the more quiet, shallow reaches of shore are 

 then selected as affording the least danger to the delicate young fish. The fact that numerous females 

 captured at Karta Bay July 11 were -all spent fish indicates that the spawning period is a brief one. 



The numljer of females seems to be in excess of the males. Of 90 fish examined at Fort Rupert, G6 

 were females, and aljout the same proportion held elsewhere. The prejjonderance of females may, 

 however, be more apparent than real. The males are considerably smaller than the females, and it 

 may well l>e that some were overlooked in the mass of material resulting from each seine haul. 



The white surf-fish will take the hook, but is too small to be of much interest as a game fish. It 

 is said to be a \'ery fair pan fish.
