GAMMARUS TENUIMANUS.

instances of such want of development or reproduction, 

 we may mention that we possess a specimen of G. marinus 

 in which one of the superior antennae is only half the 

 length of the other ; and a specimen of G. locusta, in 

 which one pair of the branches of the sixth segment of 

 the tail is only half the size of the opposite pair on the 

 same joint. 



We found this species amongst many specimens that 

 were sent to us by the Rev. Geo. Gordon, from the 

 mouth of the rivers Ness and Brauley, N.B. We 

 assume that the water must be brackish, inasmuch 

 as they were forwarded for the purpose of defining 

 the limits of the estuary by an examination whether 

 the Crustacea found therein belonged to fresh or salt 

 water. 



The following pretty sketch of Burghead, on the Moray 

 Frith, was kindly drawn for us by Mr. Small.
