A COBNTSH FATTNA. 
TOW of spines or tubercles ; terminal portion of the walking legs 
short and pointed. 
No British example of this species has hitherto been known ; 
but a specimen has come to my hands that belongs to this 
section, though I have not been able to refer it to any known 
species. 
^ It was found in a crab pot in June, 1837, and though of small 
size, appearing to the fisherman to be of rare occurrence, it was 
reseiwed for my inspection. It was scarcely the fourth of an 
inch across the carapace, the form and and colour resembling 
those of the common edible crab, but the antennse were covered 
with small wavy protuberances. On the margin between the 
ocidar cavities were five segments (lobes) the central most pro- 
jecting ; on the lateral margin were nine crenations, each, as 
those between the eyes, distinctly but finely notched. Antennso, 
small, fine, simjile, and with the palpi resembling those of the 
common crab. Hand claws and walking legs short, the two 
outer segments (joints) with a serrated crest, and the finger also 
notched at its root, walking legs with short bristles. 
It may be that it is not uncommon, as its small size may easily 
cause it to be overlooked.” 
Most probably this is the young of some known species. I 
am not aware that it has been seen by any one but Mr. Couch. 
Bell does not notice it. It appears to me to resemble Pilumnoides 
of Edwards and Lucas. 
Genus, Piluiinus. 
Second portion of the outer antennae placed in the inner can- 
thus of the orbit, and extending beyond the front. Carapace 
rounded over the summit and without lines

“ Common under stones at low water.” 
This appears to bo a widely extended species, having been 
found, according to Bell, in Mediterranean, lied Sea, East Indies, 
and other parts of the coast of Asia, Australia, and both Eastern 
and Western coasts of South America.
