102 REPORT—1857. 
recorded as Irish, whilst 803 are found in Great Britain. I have paid some atten- 
tion to this order of insects during the present summer, and have much pleasure in 
exhibiting specimens of twenty-five species captured in Ireland, and not included in 
Mr. Green’s list. They may be thus summed up :—two Papilionide ; one Sphinx ; 
five Bombyces; seven Noctuz; five Pyrales; five Geometre. There can be no 
doubt that the great discrepancy which still exists between the British and Irish lists 
of Lepidoptera would be much further reduced, even if a few districts of Ireland were 
fully worked by resident collectors : to collect successfully, local knowledge is essen- 
tial, and the hurried visit of a stranger to any district generally results in disappoint- 
ment. The West of Ireland, in particular, where many districts remain to the pre- 
sent time in much the same state as they have been for centuries, presents a wide 
field for research, and affords strongholds to species of great interest to the naturalist, 
probably to some altogether new. I may mention that ten of the species now exhi- 
bited were captured in the county of Galway. The recent discovery of Anthrocera 
Minos in the locality referred to is an earnest of what we may expect when the West 
of Ireland is thoroughly explored : this conspicuous insect occurs in great profusion, 
yet shows no disposition to wander beyond an extremely restricted locality, where 
it has doubtless flourished for ages. The following is a list of the new species :— 
Polyommatus Afgon—not uncommon near Galway in July. Erebia Cassiope— 
several specimens captured in July at considerable elevations on the sides of the hills 
between Clifden and Westport. Trochilium tipuliforme—gardens, Dublin. Setina 
Trrorella—plentiful near Galway. Liparis auriflua—Howth. Fumen nitidella— 
Howth, July 1. Clostera curtula—Tullamore. Endromis versicolor—Powerscourt. 
Acronycta aceris—Malahide. Zylophasia sublustris—at Sugar, near Galway, in pro- 
fusion. Miana expolita—near Galway, in plenty. The only previously recorded 
locality was Darlington, where the insect was discovered in 1855. Agrotis aquilina 
—Sugar, Killarney. Teniocampa gracilis—Sallows, Killarney. Dasycampa rubi- 
ginea—Ivy, Dublin. Aplecta nebulosa—Sugar, Galway. Asopia flammalis— Galway. 
Botys fuscalis—Galway. Botys pundalis—Galway. Hypena crassalis—Carrick- 
upon-Suir (Dr. Carte). Nola cucullalis—Powerscourt. Aspilates Citraria—Powers- 
court. Emmelesia ericetaria—Bray. Cabera strigillaria—Powerscourt. Macaria 
lituraria—Powerscourt. Hupithecia expulidaria—Powerscourt. 
Note on Peculiarities of Growth in Cecide. By Puriie P. CARPENTER. 
The Cecide are a group of rostriferous Gasteropoda, with shells shaped like Den- 
talium, and closed by a plug at the posterior end. There are many successive stages 
of growth, varying in shape and structure, but constant in the form of plug, which 
is of complex structure, displaying lines of growth from 4 central or lateral nucleus, 
and affords one of the best guides for the discrimination of species. As a mono- 
graph of the family was in preparation, the author sought opportunities of exa- 
mining specimens from those who were interested in microscopical inquiries. They 
were abundant in the sponge of commerce, and lived in the worm-eaten passages of 
decaying shells. 
On the Embryo State of Palinurus vulgaris. By R. Q. Coucn, Penzance. 
At the time of the publication of Professor Bell’s admirable work on British 
Crustacea, by some inadvertence the particulars respecting the embryo condition of 
Palinurus vulgaris were overlooked, and up to the present time have not been pub- 
lished. As several years have now passed, and the subject has not hitherto attracted 
the attention of any other observer, I beg to lay the following observations before 
the meeting. The metamorphoses of the decapod crustaceans may now be considered 
as established by observation made in every part of the world. The first announce- 
‘ment of the discovery came from Ireland, from experiments made near Cork by the 
late Mr. J. V. Thompson. The form under which the young decapods first appeared 
was announced as belonging to the genus Zoea, and all subsequently published 
observations have confirmed this. But in the species to which I now refer there is 
an important exception. Lest there should be any error on the matter, I have 
during the past summer again investigated the point, and have bred many thousands
