THE CKUSTACEA OF THE CHANNEL ISLANDS. 



A PAPER on this subject by Mr. Joseph Sinel, com])ri- 

 siiig a list of all the species known to him as occurring- 

 in these waters, w^as published in the Ti-ans actions of this 

 Society for the year 1906. The catalogue is almost complete 

 as regards the Stalk-eyed Crustacea, and its value is much 

 enhanced by the notes which Mr. Sinel has added with 

 respect to the habits, habitats, and general frequency of 

 the various species. The Sessile-eyed Crustacea, however, 

 wdiich include a vast midtitude of inconspicuous or micros- 

 copic forms, were less thoroughly worked up, and the list 

 contains only such species as the author had himself met 

 Avith in the course of his investigations in other directions. 



In the month of October, 1907, Canon A. M. Norman, 

 F.R.S., the distinguished marine zoologist, published in the 

 Annals and Alagazi/ic of Natural History (ser. 7, vol. xx., 

 p. 356) a lengthy catalogue of species, under the title of 

 " Notes on the Crustacea of the Channel Islands," and in 

 this paper the veteran author gives a resume not only of 

 his own researches among the Crustacea of our shores 

 during the past fifty years, but also includes all the published 

 records of other naturalists. 



By the courtesy of Canon Norman we are permitted 

 to reprint in our Transactions the main portion of this 

 important list. At first it w^as proposed merely to enumerate 

 such species as are additional to Mr. Sinel's paper ; but 

 the synonyms are so numerous and perplexing that it requires 

 a specialist to disentangle them ; and consequently it is 

 deemed advisable to give the Avhole of Canon Norman's list 

 (except the Stalk-eyed division, in which only such species 

 are noted, as are additional to Mr. Sinel's list), although 

 many of the species have already been recorded in Mr. 

 Sinel's paper under other names. 



The student is referred to the original paper for particu- 

 lars relating to synonymy, structural detail, critical notes, 

 previous records, and other points which are fully dealt with 

 by the author — as also for the names of the persons wdio 

 first found or recorded each species. In the following pages
