290 Dr. R. Koeliler on the Littoral Fauna of the 



cribriform by the presence of the " pores " (how far this 

 sarcode may belong to the epithelial cells individually, and 

 thus being agglomerated possess a general motory power like 

 that of an Amoeba or Myxogaster {zEthalium), I am not 

 prepared to say), — and the innermost layer of a soft fibro-reti- 

 culated structure, in which the fibre is composed of fibrillaj in 

 the form of elongated, linear, (?) muscular cells. The pores are 

 best seen over tlie interstices of the fibro-reticulated layer, as 

 the light then passes directly through them, when the reticu- 

 lated fibro-framework of their structure again appears to be 

 composed of the " transparent sarcode " in which the epithelial 

 cells are imbedded, rendered more or less opaque here and 

 there by the presence of an epithelial cell or two, with other 

 granular matter.

 Crustacea. 



The class Crustacea is represented at Jersey by numerous 

 individuals belonging to various species. It was to the Crustacea, 

 which interested me from various points of view, that I paid 

 attention more particularly during my visits to the Anglo- 

 Norman islands. 1 shall speak here only of the Decapoda, 

 Isopoda, and Amphipoda. The number of species that 1 can 

 record amounts to 141 ; and it is to be remarked that this is 

 nearly the number indicated by Delage in the list given by 

 him of the Crustacea of Roscoff, namely 119. 



Decapoda. 



Stenorhynchus phalangium, Edw., and tenuirostris, Bell, 

 occur very commonly among the rocks. A third and more
