THE CUMACEA OF NORTHUMBERLAND. 
By A. MEEK, M.Sc. 
We have found from time to time a few examples of this remark- 
able group of Crustaceans, and a list of the species preserved in the 
laboratory’s collections is now given. 
Family — C umidje . 
Cuma edioardsii, Goodsir (as defined by Sars). 
This species has been obtained at several places in the northern 
part of the district as well as at Cullercoats. It was caught in Holy 
Island harbour, in August, 1897, June, 1898, and again in 
September this year. In August, 1899, it was got at the surface in 
Skate Roads. At Cullercoats, it was taken 3 — 4 miles off on 31st 
August this year at the Northumberland Coast Club’s dredging 
excursion. 
Localities : — Holy Island and Skate Roads, Cullercoats. 
Iplunoe trispinosa (Goodsir). 
Cullercoats, 31st May, 1899— one male. 
F amily — Leuconid.e . 
Eudorellopsis deformis (Kroyer). 
Cullercoats, 31st May, 1899. 
Family — Diastylid.e . 
Diastylis rostrata (Goodsir). 
Several specimens have been obtained off Cullercoats, and even 
in the harbour. 
Diastylis spinosa, Norman. 
Females have been obtained at Cullercoats (31st May, 1899, 
4th September, 1900), and at Druridge Bay (30th June, 1897). 
The specimens agree with Norman’s D. bradyi, the female of 
this species, but differ in the following respects : — the blunt teeth 
on the edge of the carapace are restricted to the anterior portion, with 
the exception of two which are isolated on the ventral border ; the 
terminal spines of the telson are strong, the 3 — 4 pairs of lateral 
spines are weak. The spines on the inner uropod are arranged as 
follows — 8 on the first, 1 on the second, and 1 on the last segment. 
Dr. Caiman, Dundee, kindly gave me very complete references 
to the literature bearing on this species, at the same time expressing 
tlie opinion based on my description that my specimens were 
females of D. spinosa.
