that it descends to very considerable depths." The writer has taken it in water of 

 less than 5 fathoms in Puget Sound, and he obtained a specimen caught from 

 the Monterey wharf in water of about 3 fathoms. He also secured over a score of 

 immature specimens (measuring about 30 cm. ) from a single haul of a seine along a 

 shore reach near Port Townsend, at a de]ith not greater than 2 fathoms. It is 

 known, furthermore, that egg-cases of this species are plentiful in shallow water.

 from 10 to 50 and from 22 to 150 fathoms. It appears, further, that Callorhyn- 

 chus is .sometimes taken in water of no great dei>th. (Thus Plate records having 

 dredged ofif the coast of Chile an egg-capsule in water of 10 fathoms.) It follows, 

 therefore, that in the matter of vertical distribution Chimferoids are not widely 

 different from sharks.

Returning to the habitat of C. colliei : It can safely be said that this species 

 is more abundant in shallow water in Puget Sound than at similar depths on the 

 California coast — in this regard paralleling several other fishes as well as inverte- 

 brates. It is nevertheless true that in the region of Monterey specimens were often 

 taken in water shallower than 1 5 fathoms ; but experience demonstrated that the 

 greatest number of individuals could be fished in water of 60 fathoms. It was also 

 found that in somewhat deeper water, 60 to i 20 fathoms, females, although less
