256 Mr. Thompson's Additions to the Fauna of Ireland, 



Callianassa suhterranea, Leach, Mai. pi. 32. Edw. Crust, t. 2. 

 p. 309. 



Cancer Astacus suhterraneus, Mont. Linn. Trans, vol. ix. p. 88. 

 t. 3. f. 1, 2. March 25, 1839. On examining the contents of 

 the stomach of several individuals of the Platessa Pola, which 

 were taken early this morning off Newcastle (county Down), 

 two of the larger arms of this species, so peculiar in form and 

 still retaining their beautiful pink colour, were detected. 



Pasiphcea Sivado, Risso, Hist. Nat. I'Eur. Merid, t. 5. p. 81. ed. 

 1826. Edw. Crust, t. 2. p. 426. In the British Museum 

 there is a specimen so named, and labelled " Ireland." From 

 the donor, the Rev. James Bulwer, I learned that it was taken 

 by him in the vicinity of Dublin. 



Demmine spinosa, Leach. Desm. Gen. Cons. Crust, p. 263. 

 pi. 45. f. 6. 



Cancer gammarus spinosus, Mont. Has occurred to me not uncom- 

 monly on the north-east coast. 



Dynamena rubra. Leach, Desm. p. 298. As last. This species was 

 determined from comparison with Dr. Leach's specimens in the 

 British Museum. 



^ga bicarinata, Leach, Desm. p. 305. March 30, 1839. I pro- 

 cured an individual of this species alive in Belfast market, 

 whither it was brought with oysters from Carrickfergus. It 

 was not known to Dr. Leach whence the specimen was brought 

 that served for his description, and the works accessible to me 

 in which the species is introduced do not contain any informa- 

 tion as to its habitat. 



Caprella linearis, Latr. Johnst. Mag. Nat. Hist. vol. viii. p. 672. 

 f . 7 1 . Found among marine plants collected near Glenarm by

 abundance by Mr. Hyndman and myself upon Plumulariee, &c. 

 dredged in Strangford lough. 



Bopyrus squillarum, Latr. Desm. p. 325. t. 49. f. 8 — 10. A Palamon 

 serratus, taken by Mr. R. Ball at the South Islands of Arran, 

 off the coast of Clare in June 1835, contained within the plates 

 of the head a fine specimen of this Bopyrus 6 J lines in length, 

 and agreeing with the female as represented by Desmarest and 

 other authors.
