CALIFORNIA FISH AND GAME. 157 
The evening of August 19, five months after having been received, 
the egg case was hanging perpendicularly in the water with the 
smaller end up, and the head of the fish toward this end. During the 
night the shark struggled up through this small end, splitting it entirely 
across the top, freed itself from the case, and was found the next 
Fic. 42. Swell Shark, Catulus wter, the day after hatching. Natural size. 
morning reposing on the bottom of the aquarium. The egg case was 
then examined and it was found that beyond! this opening through 
which the fish had slipped the case was unbroken. One of the slits 
at this end had aided in making the exit a little larger. The shark 
was very inactive and remained in one place for a long while, only 
occasionally moving the fins or tail slightly. During the day it moved 
about somewhat on the bottom of the aquarium. The next day it was 
taken out and identified as Catulus uter, Jordan & Gilbert. 
Figures showing the egg case and the fish immediately after hatching 
accompany this article.

wonder why? 
Angler: The fish we caught were stream fish and were in the pink 
of condition, for they had been feeding on insects, which is the best 
kind of food for a trout. Furthermore, they were in their natural
