224 CRUSTAC KA OF iiii-: ('iia\.\i:l isi.axds. 



lone thoraeica, Moit. On tlu; L^ills of ('((lliaiKtssa snhto-raiica. Rare. St. 

 Clement's Bay, Jersey. 



PHYLLOCARIDA. 



Nebalia bipes, F((hr. This curious little crustaceuu yeems to be a Burvival 



of an ancient type having affinities with all existing- types in general and 

 none in particular. Found under stones amongst decaying seaweed, and 

 most abundant where the conditicms are most unsavour}'. Common in 

 suitable habitats. 



ENTOMOSTRACA. 



It is in this order that the great numerical strcuoth of the 

 class Crustacea lies. To attempt a list in the present state of 

 our knowledge would be absurd, for the marine Entomostraca 

 of the Channel Islands offer a vast field of research. Only a 

 few weeks ago, whilst on the seashore collecting for a short 

 time with the Rev. Canon Norman in the high-tide pools at 

 St. Clement's, Jersey, I noted that as many as eight or ten 

 different species were obtained in one or two strokes of a small 

 net six inches in diameter. So that our local marine Ento- 

 mostraca may be described as a terra inco(jnit((^ and therefore 

 the uselessness of my cataloguing the few s])ecies that are 

 known to me will be at once apparent. Baird's Brithh 

 Entomostraca is the best text book for the young student, but 

 later publications have immensely increased the number of 

 described species. 



CIRRIPEDIA. 



The Barnacles are now included among the Crustacea, 

 although formerly they were treated as a distinct class. 

 Compared with some of the foregoing orders, they are not 

 very numerous, and the following species are given merely as 

 a rudimentary list. Others must certainly occur here. 



Balanus balanoides, Xi;^ Acorn Barnacle. Abundant, coating rocks and 



sea-walls up to high tide level. 

 Balanus tintinnabulum, Lin. On rocks at low water, on large crabs, &:c. 



Larger than the last, and less common. 

 Conehoderma graeile, IleUer. Not common. Off St. Martin's Point, 



Guernsey, dredged. Extreme low tide, St. Clement's Bay, Jersey. 

 PeltOgaster pag'Url, Rathke. Frequent ; but by no means abundant. 



Parasitic on the Common Hermit Crab 

 Saeeulina eaPCini, Tkomp. Tolerably common. Parasitic on the Edible 



Crab, rarely on other species in these islands. 



In closing this pai)er I feel very keenly that, after deal- 

 ing with the Stalk-Eyed Crustacea, wbich I think have now 

 been catalogued pretty exhaustively, I have simply been guilty 

 of the proverbial " rushing in " where others, with more prac-
