Annelida. 



Nemertes gracilis, Johnst., Mag. Zool. and Bot., vol. i. p. 534. pi. 

 17. f. 1. Nov. 12, 1840. I received a specimen of this worm 

 taken at Cultra, Belfast Bay. It is larger than Dr. Johnston's, 

 but agrees in every character with his description and figure. 



. lactiflorea, Johnst., Mag. Z. and B., vol. i. 535. pi. 17. 



f. 2. With the last species, two examples of this were pro- 

 cured. The eyes are as described by Dr. Johnston, and conse- 

 quently the worm would seem to be distinct from Planaria ro- 

 sea, Mull. My specimens when extended are each about two 

 inches in length and of a yellowish flesh colour. The characters 

 are all as given by Dr. Johnston. 



Phylline Hippoglossi, Lam. Johnst., Annals Nat. Hist. vol. i. 431. 

 pi. 15. f. 1—3. 



Hirudo Hippoglossi, Mull., Zool. Dan., vol. ii. p. 18. t. 54. For some 

 years past this species has commonly occurred to me on Halibut 

 (Hippoglossus vulgaris) brought to Belfast market, and captured 

 on the coasts of Down and Antrim. 



Carinella trilineata, Lined Worm. Johnst., Mag. Nat. Hist., vol. vi. 



Gordius annulatus, Mont., Linn. Trans., vol. vii. p. 74. This beau- - 

 tiful worm has been dredged by Mr. Hyndman and myself on 

 different occasions in Strangford Lough and in the open sea at 

 Ballywalter on the Down coast : in every instance it was free. 

 Belfast Bay, Dr. Drummond. 

 Glossipora tuberculata, Johnson (J. R.). Neighbourhood of Cole- 

 raine, Mr. James Bryce, jun. 



Crustacea. 



Pisa tetraodon, Leach, Mai. Brit., pi. 20. Mr. R. Ball has in his ca- 

 binet a specimen found at Roundstone by Mr. McCalla. This 

 species is given in Mr. Templeton's catalogue of Irish Crustacea, 

 but I have reason to believe by mistake. 



Ebalia Cranchii, Leach, Malac, tab. 25. f. 7 — 11. July 1840. A 

 single specimen dredged in Roundstone Bay, Connemara, by 

 Mr. R. Ball and Mr. Forbes. Several since obtained by Mr. 

 Ball, thrown on shore at Portmarnock by a storm. 



Inachus leptochirus, Leach, Malac, tab. 22. B. A specimen dredged 

 in Chfden Bay, Connemara, about the same time with the last. 

 Belfast Bay, Mr. R. Patterson. 



Athanas nitescens, Leach, Malac, t. 44. 



Cancer nitescens, Mont. M.S. A specimen taken between tide-marks 

 at Lahinch, co. Clare, Mr. Forbes and W. T. 



ASga tridens. Leach. An JSga agreeing in the few characters as- 

 signed to this species by Dr. Leach is in my collection. It was 

 taken alive on a cod-fish in Belfast market.
