REV. A. MERLE NORMAN, M.A., ON THE CRUSTACEA. 279 
(Goodsir), or Macromysis (White) must be merged in Myszs, the 
male of which it represents. I believe also that I recognise 
Goodsir’s Cynthilia Plemingii in the male of another Mysis, which 
is abundant on this coast, and which if it be not Cynthilia Flem- 
tng is as yet undescribed. The male Mysis, to which I refer, 
agrees with the description of Cynthilia Flemingii in all respects, 
except that a ‘minute organ” which zs attached to the abdominal 
feet is not “‘convolute,” and is totally different in character from 
the true ‘“‘convolute organ” of Cynthilia (Cynthia) Thompsoni 
(Edwards); and the question is, did Goodsir describe the organ 
erroneously. 
Haploops tubicola (Liljeborg). Seven miles off Tynemouth, 
and in deep water off Berwick. The genus is new to Britain. 
Gidicerus parvimanus (Bate and Westw.) was dredged from 40 
to 100 miles off Tynemouth. And I also procured it last year 
when dredging in 25 fathoms, about seven miles off Seaham. 
Only a single specimen—the type in my collection—was previously 
known. 
Kroyera altamarina (Bate and Westw.). One specimen—the 
second known—taken 100 miles east off Tynemouth, in 25-30 
fathoms. 
Dexamine Vedlomensis (Bate and Westw.). This species was 
described from a single example procured by myself last year in 
Vedlom Voe, Shetland. The five specimens now taken off this 
coast make us better acquainted with the species. The antennz 
in all the specimens have the same characters, and the notch on 
the fourth segment of the pleon is deeply cut, and has the anterior 
edge produced and projecting backwards, so as to overhang the 
notch (see the figures in the British Sessile Eyed Crustacea); 
another apparently constant specific character is afforded by the 
backs of the second and third segments of the pleon not only 
being strongly toothed posteriorly as in D. spinosa, but also 
minutely serrulate. ‘The dorsal armature varies considerably ; 
three of the specimens from this coast agree with the type; a 
fourth has no spine on the last segment of the pereion; and the 
fifth has no spines on the last segment of the pereion, and the 
first of the pleon. The colour is white, with the eye, mouth,
