HIGHER CRUSTACEA OF THE L.M.B.C. DISTRICT. Fal 
*Tphinoe trispinosa, Goodsir. 
II., E.L. Three males. Port Erin. These were the 
variety without the serrated dorsal crest. 
*Pseudocuma cercaria, Van Beneden. 
II., E.L. <A very large number, all males, at Port Erin. 
This is certainly the species described under the above 
name by G. O. Sars,+ but it is difficult to believe that 
Van Beneden’s{ figures and description (which Sars 
remarks are ‘‘faulty in the extreme’’) can refer to the 
same. Our experience in the ‘‘ Hyzna’”’ confirms Norman’s 
statement, that this is ‘‘the most numerically abundant 
species of Cumacean in the British seas.’’§ 
ISOPODA. 
*Anceus maxillaris, Mont. 
Ill. A specimen of the Praniza form of this (?) species, 
taken in a rock pool at Penmaenrhos, attached to a young 
Cottus behind the second dorsal fin. Colour, brilliant 
blue-green. 
Janira maculosa, Mont. 
II. A number of specimens on a mass of Alcyoniwm 
digitatum, dredged between the N.W. Lightship and Isle 
of Man, on the outward trip of the ‘‘ Hyena,” 19th May, 
1888. 
*Munna fabricu, Kroyer (Pl. XI., figs. 16 to 18). 
I. A single specimen, without the long ambulatory legs 
and long outer antenne. ‘The telson agrees with Kroyer’s
