220 The Irish Naturalist. July, 



He also alludes in another note to ten Macrura which had 

 hitherto been unrecorded from the British and Irish area, and 

 which were taken by " Helga" off the west coast of Ireland. 



In the Annals of Nat. Histo?y Mr. Tattersall 1 gives us a 

 preliminary description of six new forms of Opossum Shrimps 

 (Mysidae) from a considerable depth off the west coast of 

 Ireland. Two of these belong to new genera (Bathymysis 

 and Metamblyops). 



The first part of Mr. Pearson's list of Irish Marine Copepoda 

 has already been alluded to by Prof. Carpenter. He now 

 publishes' the second portion, including the pelagic species. 

 In every case the vertical range of the species, as well as the 

 general distribution, is indicated. 



The pelagic Amphipods are described by Mr. Tattersall 3 in 

 an interesting paper on the species frequenting the Atlantic 

 slope. Over twenty species are recorded as new to the Irish 

 marine area, among them one belonging to a new genus 

 (Metacyphocaris). Mr. Tattersall's observation on the four 

 kinds of Amphipods which are known to form a very large 

 part of the food of three of our principal food fishes during 

 the late autumn and early winter, brings to our minds the 

 practical utility of the study of these and other marine 

 organisms. 



Moixuscs. — A single specimen of the prosobranch gastro- 

 pod, Lamellaria pellucida, is recorded 4 by Mr. Farran 

 from off the Fastnet Rock, county Cork. He referred the 

 specimen to the American variety Gouldi rather than to the 

 type. 



Tunicates. — The Tunicates are, perhaps, the most ne- 

 glected group of Irish marine animals, on account of the 

 extreme difficulty of their determination. It is with particular 

 pleasure, therefore, that we notice that Mr. Farran has had the
