VI. Description of a new Irish Crustaceous Animal. 
Robert Templeton, Esq., R. A. 
[Read September 7, 1835.] 
(Plate V.) 
A short time since, I received from my friend R. Patterson, Esq., 
Vice-President of the Belfast Society of Natural History, speci- 
mens of Irish Crustacea, the greater part of which, though not new 
to the British fauna, are yet met with but rarely, and the whole, 
with one exception, not recorded by my father as natives of our 
Irish coast. As however I have not yet had time to give them all 
a thorough examination, I shall defer notice of any excepting two 
species which present some singular peculiarities, and tend to re- 
move in some measure the doubts which have existed as to the 
proper position in the scale of animated beings to be assigned to 
one of them ; since a similarity, I conceive, may be traced between 
the organs of manducation in these, and in genera whose posi- 
tion has been correctly ascertained, sufficient to warrant their being 
associated : data are also offered us from whence to infer the accu- 
racy of a surmise of the celebrated Latreille, whose sagacity and 
penetration stand in estimation so deservedly high, that any thing 
tending either to confirm or disprove his views, derive from that 
circumstance alone increasing interest. 
The first of these specimens I imagined at first glance to be a 
Nebalia ; it however proves remarkably distinct and requires the 
establishment of a new sub-genus. I received eight specimens, 
six of which have been sacrificed in the examination of the mouth, 
and the two remaining I forward to be placed among their con- 
geners in the Society’s collection.
