other species of the genus, except that on all my specimens 

 there is a very short cylindrical appendage attached underneath 

 to the third segment on the right side. A hemispherical portion 

 at the end is very dark violet, covered with numerous small 

 spines (fig. 13 a) and surrounded by a nan'ow light yellow 

 border {b), on which they are rather larger and more scattered. 

 There are a few hairs on the violet part. The end, therefore, 

 resembles a hemispherical file, but I cannot ofi"er the slightest 

 suggestion as to its probable use. Mr. Darwin and Prof. Que- 

 kett have kindly examined it for me. The females have no such 

 appendage.

XIV. — Notes on some new or little-known Marine Animals. 

 By P. H. Gosse, A.L.S. 



To the Editors of the Annals of Natural History. 



Gentlemen, 



The expectation which I ventured to express in your Magazine 

 for last October has been amply reahzed. Marine animals and 

 plants have been exhibited in London, in their native health and 

 beauty, in circumstances where their various functions and in- 

 stincts can be carried on under the eye of the naturalist ; and the 

 inhabitants of the metropolis have enjoyed a sight of the curious
