GAMMARIM. 



L. nasuta of Dana, taken on the coast of Brazil, and 

 L. variegata, taken by Mr. Stimpson in Simon's Bay, 

 Cape of Good Hope, except, perhaps, in size, can with 

 difficulty be distinguished from this species. L. Magel- 

 lanica of Edwards, brought from the southern extremity 

 of South America by M. D'Orbigny, also bears to it 

 a close general affinity, but differs materially in size : 

 the British species being probably the smallest of the 

 genus, whilst the Magellan form is the largest, and pro- 

 bably also the largest known normal Amphipod, being 

 about three inches in length, forming a fit companion to 

 Uristes gigas of Dana, and Cystosoma of Guerin. 



The accompanying vignette of Audleyn Castle, on the 

 coast of Co. Down, Ireland, was kindly sketched for us 

 by Mrs. Campbell, of Stoke, Plymouth.
