10 LIVERPOOL BIOLOGICAL SOCIETY. 
et de la Belgique,’ 1888), which the author has been kind 
enough to send me, I was able to identify all the specimens 
dredged off the Isle of Man as belonging to this species. 
It is best distinguished by the strong tooth on the inner 
side of the merus joint of the third maxillipedes being 
connected with the distal extremity of the joint by a ridge 
on which are two to four smaller teeth. 
*Munida bamffia, Pennant. 
II. One specimen. Notwithstanding the high authority 
of Mr. G. O. Sars, who considers M. rugosa, Fabr., as 
distinct from M. rondeletii, Bell,+ I agree with M. Bonnier 
and others in holding them to be the same, and therefore 
referable to the older name of Pennant. Mr. R. Pocock, 
of the British Museum, and I examined a large number of 
individuals at that institution, and found them to vary so 
much in the characters relied on by Sars that it was 
impossible to separate the two forms. 
MACRURA. 
*Caridion gordom, Sp. Bate. 
II. One female, with ova, between Calf of Man and 
Port Erin. 
Pandalus brevirostris, Rathke. 
II. Several between Calf of Man and Port Erin. 
CUMACEA. 
*Cuma scorpioides, Montagu. 
Il., E.L. Two young males. Taken by electric light 
(E.L.) at Ramsey. Recognizable by the lateral carina 
extending longitudinally from the rostrum across the 
carapace and free thoracic segments (see Norman, “ Brit. 
Assoc. Report,” 1868, p. 273).
