consisted chiefly of Siridla norvegica (Sars), mostly 

 young ; and Macromysis inermis (Rathke) among 

 Scliizopoda ; and of Apherusa bispinosa (Bate) and 

 Paratylus swammerdamii (M. Edw) among Amphipoda. 

 The total number of species was 19. Of these six were 

 Podophthalmata, one Cumacean, two Isopoda, and ten 

 Amphipoda, all previously recorded. 



A third bottle contained Chelura terebrans, Philippi, 

 from the wooden piles of Ramsey Pier. 



The fourth contained Amphipoda, &c, from Calf of 

 Man, collected at low spring tide on September 11th. 

 The most abundant species in this were Stenothoe 

 monoculoides (Bate), and Jassa (Podocerus) variegata 

 (Bate and Westwood). [See "Trans. I/pool Biological 

 Society," Vol. IX., page 315.] 



I retain the generic name Jassa, of Leach, 1815, in 

 place of Para jassa, Stebbing, as I fail to see why it should 

 be displaced by a genus of fossil fish founded in 1839. 

 The bottle also contained several Idoteas too young to be 

 identified with certainty, and a few specimens of 

 Janiropsis breviremis, Sars. This species has not been 

 previously recorded from Liverpool Bay, nor indeed from 

 British waters, except a single female taken by me 

 between tide marks in Yalentia Harbour, Ireland. It is 

 easily mistaken for young Janira maculosa, Leach, from 

 which it may be distinguished by the different form of 

 the operculum of the male and the much broader palp of 

 the maxillipedes. 



This bottle also contained five or six Pycnogonida, 

 which Mr. G. H. Carpenter, who has kindly examined 

 one, considers to be young specimens of Ana plod actylus 

 virescens (Hodge). Two were still in the hexapod state, 

 and a male had the false feet five- jointed as in 

 Phoxichi lidium, instead of six-jointed as in adult
