RECENT CHLMsEROIDS 



Chimaera, the third genus of the recent forms, is well 

 represented in the commoner form, C. monsti'osa (Fig. 1 19, 

 A, B}. This species is widely distributed in the Mediter- 

 ranean and Atlantic, taken usually in deep water; it is the 

 largest of the living species, often attaining a yard in 

 length. Its occurrence is usually erratic: in a favourable 

 locality, as at Messina, months often elapse before one is 

 taken ; at other times many will be brought in in the 

 course of a few days. The Portuguese species, C. affinis,

 in length, differs sharply from the other species, and is 

 therefore often given rank as a distinct genus, Hydro- 

 lagus, Gill. The writer learns from his friend Dr. Bean
