NUDIBRANCHIATA. 
277 
Genus Calliopjea. 
C. bifida , Mont. 
An individual of this species, taken by Mr. Getty and' Mr. Hyndman 
when dredging in Belfast Bay, was brought to me. It agrees critically 
with Montagu’s description, except in the following points. There 
are just twelve appendages on each side, three of which are larger than 
the rest, but placed at unequal distances from each other on both sides, 
and not opposite, as shown in Montagu’s figure. The colour is better 
defined than in the figure ; the marginal line, whence the appendages 
issue, is strongly marked and reddish, as they likewise are; foot plain 
flesh-colour. 
The animal is extremely agile, and, planaria-\\k.e, is one moment twice 
the length it is the next ; it often moves about with the foot upwards, 
and in its motion several times had the long tail thrown quite under the 
head. 
Genus Eolis. 
E. papillosa, Johnst. 
Of this fine species, three individuals were found by Dr. Lloyd (of Ma- 
lahide) and myself, under stones at Lambay Island, on the 1st of June ; 
at the same time their spawn, just as described and figured by Dr. John- 
ston in Mag. N. H. as above-cited, was obtained. One of these animals 
examined critically had 25 lateral rows of branchial processes, and about 
12 of these to each row. 
E. Zetlandica, Forbes. 
July 29th , 1840. — This species was taken by Professor Forbes and my- 
self, between tide-marks, at Lahinch, County Clare. 
E. Cuvierii. 
Among the Nudibranchia which I owe to the kindness of Professor 
Allman, was a small individual of this species, taken by him at Court- 
masherry Harbour, in the autumn of 1838. 
E. coronata, Forbes. 
At Glandore Bay, found to be common at Malahide, by Mr. Alder and 
Dr. Farran. 
E. pallida, Aid. and Hanc. 
A single example taken at Malahide with the preceding. 
E. alba, Aid. and Hanc. 
Dublin Bay, Messrs. Alder and Hancock. 
E. Farrani, Alder and Hancock. 
Dredged at Malahide, Messrs. Alder and Farran. 
E. violacea, Alder and Hancock. 
Mr. Hyndman, when dredging on the 26th August last, off Castle Chi- 
chester, Belfast Bay, in 6 to 10 fathoms water, captured a specimen of 
this very beautiful Eolis. It was brought to me alive, and immediately 
afterwards despatched by post in a phial of sea-water to Newcastle, for 
Mr. Alder’s examination in a living state, but on reaching its destination 
was unfortunately dead. Mr. Alder remarked, that it was a very fine 
example of his E. violacea, which was described from a Cullercoats spe- 
cimen smaller and less perfect than this had been.
