third, fourth, and fifth segments fused, the sixth very small

maxillipedes. 
g. Length and width of carapace 11 millim.; length of

A number of specimens of this species were dredged by 
the ‘Porcupine’ in the Mediterranean. Some of these 
specimens were presented to the British Museum by the 
Rev. A. M. Norman and were labelled “ 2. nux, Norm.” 
This name is included in the list of the species composing 
the Museum Normanianum, and also in the list of the species 
of Ebalia given by Mr. Miers in his Report on the Brachyura 
of the ‘ Challenger.’ But no description of the species has yet 
been published. I have consequently taken this oppor- 
tunity of characterizing it and have selected as types an adult 
male and female specimen belonging to the series dredged in 
the Mediterranean. In some of the small specimens of this 
series the larger tubercles on the gastric region of the 
cephalothorax are wholly absent. 
A single damaged male specimen was obtained by Mr. 
Green at a depth of 315 fathoms. This specimen differs 
from all the Mediterranean forms that I have seen in having 
the legs almost wholly smooth. 
Munida bamffica (Pennant). 
Two specimens from 250 or 315 fath. 
Although Prof. G. O. Sars has attempted to show that 
M. Rondeletii is specifically distinct from JL rugosa, never- 
theless I agree with my friend Mr. A. O. Walker in thinking 
that the two names must be referred to one and the same 
species, which, in accordance with the laws of priority, must 
be termed J. bamfjica, Pennant. 
Eupagurus bernhardus (Linn.).

Eupagurus, see Henderson, “ A Synopsis of the British Paguride,” 
Proc. Phys. Soc. Edinb. 1886, p. 65.
