1. Remark on the Genus Noctitula of J.V. Thompson ; by J J.D. Dan 
—The genus Nocticula established by Thompson in his Zoological Re. “f 
searches, No. 2, p. 52 and plate 5, (Cork, 1829,) is closely related to 
the Euphauside.* The general form of the animal, its thoracic and 
abdominal appendages, and the antennz, eyes, and short beak, are as in 
Thysanopoda and Euphausia ; and the last abdominal segment has the 
acuminate a with the naked barb either side near apex, which 
_in the suggestion of this error we make the ‘due allowance for draw- 
made at sea of such minute objects” which Thompson asks of 
’ chis readers. ) The number of thoracic legs is stated at sixteen, but this " 
includes, as the drawing shows, a pair of maxillipeds. Excluding these, 
there will then be 7 pairs, which is the number in Thysanopoda ; ‘an 
it seems probable that Nocticula and Thysanopoda are identical, and 
if so, the former name has the prece ‘ 
The species described and figuied by Thompson, was taken in the 
Atlantic, between latitudes 5° 25’ S., and 29° 30’ N., and longitude 
17° 18 W., and 32° 55’ W., on the 6th, 12th, and 25th of September. 
It was brilliantly phosphorescent. It is called the Nocticula Banksii, 
as it is supposed by Thompson, and with apparent good reason, to be 
identical with the Cancer fulgens of Sir Joseph Banks, a species ob- 
served between Madeira and Brazil, and published with a drawing by 
Macartney in the Philosophical Transactions for 1810. This drawing, 
mpson has copied, and in it 7 pairs of thoracic legs are represented. 
2. Observations on some Crustacea, in the collections of the Academy 
of Natural Sciences at Philadelphia; by Prof. L. R. Ginpes ct Charles- 
‘ton, 8. C., (Proc. Acad. Nat. Sci., Philad., Mash $800. v, 25.)—The 
Chorinus armatus of Randall (Memoir in Jour. t. Sci. Philad., viii, 
106,) is a Pericera, and agrees with Padane forwain of Edwards 
(Crust., i, 335. 
The Cancer mercenaria of Say, is a Pseudocarcinus. It is referred 
by Edwards with some doubt to the genus Xantho of Leach (M. Edw 
le i, 399); but his description of Pseud. ocellatus applies in every 
particular to the mercenari Me 
Grapsus Lonaipes, Randall, is Grapsus cruentatus, according to 
Gibbes, and the statement that Surinam is its locality, is considered a 
istake. 
Grapsus HIRTUS, Randall, is G. rudis, M. Edw., the latter name 
having the priority. 
Guat ornata, Randall, is an Ilia, and a distinct species. 
To the above, the Committee of the Society add—that Macrophthal- 
mus seainarsinars Randall, (published in 1840,) is Gelasimus telescopi- 
» Owen, bo of Blossom (1839), and M. podophthalmus, Voyage 
of Bonite, (1841. 
Pacuranarsvs PARALLELUS, Randall, is Grapsus Thukujar, Owen,
