ARTHROPODA 



Class CEUSTACEA 



The crustacean fauna of the Mount Desert Region is not 

 dissimilar in its general facies to what would be expected 

 anywhere north of Cape Cod. It is unfortunate that we do 

 not have a fairly complete view of the Crustacea of some 

 locality on the northern Massachusetts coast, Gloucester, for 

 example. I note this point since it is still an open question 

 whether Cape Cod marks the only faunal boundary on the 

 Xew England coast. 



Turning to a comparison of the crustaceans of this region 

 with those of Woods Hole, a very striking fact is the occur- 

 rence at Mount Desert of notodelphyoid and chonistomatoid 

 Copepoda, which Dr. C. B. Wilson tells me are entirely absent 

 at Woods Hole, except for Choniosphaera. Further, the 

 Mount Desert fauna quite lacks the species of Mediterranean 

 affinities which are a conspicuous part of the Woods Hole 

 fauna. 



A few forms, for example, ParathaJesfris jacl'soni and 

 Cytheropteron pyramidale, give a distinct Arctic facies to the 

 group. On the whole, however, the Crustacea resemble those 

 of Norway and the Maritime Provinces of Canada, and the 

 fauna is definitely lacking in southern species.
