carnivores, the latter part of the book deals particularly with the in- 

 habitants of the country and the difficulties that confront the explorer. 



The translation is in the main good, though marred here and there 

 by a grammatical error and by a certain looseness of expression, as- 

 where scorpions are termed "reptiles," and hippopotami are famil- 

 iarly spoken of as "river hogs"; the use of capitals for the authority 

 of Latin names seems also to have afforded a stumbling block. An 

 index might have added to the usefulness of the book.

Notes .— Recent Extension of the Range of the Green Crab. About 

 the year 1892 or 1893, I first began to notice at Cohasset, Mass., an 

 occasional specimen of a green crab. These crabs were about two 

 inches in diameter and were seen at low tide on the mud flats about 

 our float in company with Cancer irrorata. From that time on 1 

 noticed a gradual increase in their numbers but thought nothing of 

 it until 1902, when a reference to a "green crab" in a physiology lec- 

 ture made me wonder if the crab which had recently become so abun- 

 dant at Cohasset was the same as that experimented upon. On 

 submitting specimens to Dr. Walter Faxon for determination, I learned 

 that they were Carcinides mwnas, a species that was not believed to 

 occur north of Cape Cod. In the course of the summer I collected 

 specimens at the following additional localities: Nahant, Lynn, and 

 Ipswich. Mass., and Kitt.Tv. Maine. In the same year (1902) it was 

 coHcclc<l ar Maiiomct P..i>it, Mass., by Mr. J. A. Cushman, and a 

 record of its nrciirn ncc at Portland, Maine, was obtained by Dr.
