(6) CUMACEA. 



The species of the. Cumacea which have been identified are : — 



Iphinoe trispinosa (Goodsir). Diastylus rugosa, G. 0. Sars. 



Cumopsis goodsiri (V. Boneden). Pseudocuma cercaria (V. Beneden). 



Leucon nasicus, Kroyer. Gampylaspis rubicunda, Lilljeborg. 



Eudorella truncatula (Spence Bate). Petalosarsia declivis, G. 0. Sars. 



Others are recorded simply under the family or generic names. As 

 these crustaceans usually live on or close to the bottom of the water, the 

 records of them in the tow-net lists are, as might be expected, compara- 

 tively few, and may be briefly stated as under : — 



Iphinoe trispinosa is only recorded for Station I. in July 1889, and 

 for the same station in February and July in 1890. 



Cumopsis goodsiri. The only record for the species is for Station III. 

 in September 1891. 



Leucon nasicus. In 1890 this species is recorded for Station I. in 

 April, for Station V. in March, and for Station VIII. in December ; in 

 1892, for Station V. in April, and for Station VIII. in May 1895. 



Eudorella truncatula. The records for this species are four in number, 

 one for Station V. in September and one for Station VIII. in December 

 1890 ; one for Station I. in February 1892, and one for the same station 

 in June 1893. 



Diastylus rugosa is recorded under its full name only for Station I. in 

 April 1890, and for Station V. in {March 1891 ; but there are several 

 records of Diastylus sp. included in the additional references to the group 

 under the more general name of Cumacea, etc. 



Pseudocuma cercaria. This is a moderately common Cumacean, 

 though, for the reason stated about the habits of these creatures, its 

 name does not occur very frequently in the lists of tow-net fauna. The 

 records are as follows : — In 1890 there are four in April — viz., one for 

 Stations I., V., VIIL, and IX., and it is recorded again for Station IX. 

 in August and October. In 1891 there is a record for Station IX. in 

 February, and for the same station again in September, and there is also 

 one for Station VIII. in September. In 1892 there is a record for 

 Station I. in January, and again for the same station in September. 

 There is only one record for 1893 — viz., for Station VIII. in April. In 

 1894 there are records of Pseudocuma for Station V. in August, and for 

 Station IX. in February and April; and in 1895 for Station I. in April 

 and October, for Station III. in October, for Station V. in April and 

 August, and in the same two months for Station IX. 



Campylaspis rubicunda. This species, which at that time had not 

 been recorded for Britain, was observed at Station IX. in April 1893, 

 and at Station V. in 1894. 



Petalosarsia declivis, another rare Cumacean, was observed at the 

 same time and place as Campylaspis. This concludes the records of the
