Type. — c? ^i^d 9, U. S. National Museum, No. 10919. 



As indicated by the above key this species is most nearly allied 

 to C. gundlachi but its larger size will readily serve to separate it from 

 both that species and C. delicatida. 



GENERAL. 

 THE SPECIALIST. 



By a. N. Caudell, 

 Washington, D. C. 



Broadly speaking the general zoologist is as old as history, but the 

 specialist as now known is a product of the last century. In the days 

 of Ray and Linnaeus, when the known species of even large groups 

 were numbered in scores only, the specialist was unknown and un- 

 needed. The naturalist of a little more than a century ago could 

 cover the entire field of zoology, considering the forms down to the 

 species. For any one at the present time to attempt covering the 

 same field would be preposterous. The general zoologist of to-day 

 must deal with his subject as classes and groups, descending to genera 

 and species only occasionally for purposes of illustration. If he deals 

 with species he either proves superficial or chooses a restricted field to 

 labor. In other words he becomes a specialist, for the field of zoology 

 is now too large for any one person, no matter how brilliant, to master 

 in its entirety. 



It is the innumerable contributions to knowledge made by the 

 specialist that have brought the ingenious but crude systems of Lin- 

 naeus and Cuvier to the present state of comparative perfection. The 

 advancement of zo51ogy as a whole depends upon the knowledge of 

 the species, and it is the specialist, confining his efforts to restricted 

 fields, that is responsible for the proper researches being made. The 

 smaller the field, other things being equal, the more thoroughly can 

 it be covered. We cannot know all things, so let us know something, 

 but know it well.
