Journal of a third voyage for the discovery of a north-west passage from the 

 Atlantic to the Pacific ; j)erformed in the years 1824-25, in his Majesty's ships 

 Hecla and Fury, under the orders of Captain William Edward Parry, R.N., F.R.S.,

In the Appendix, whicli is separately paged, under " Natural History " is included a paper entitled 

 " Zoology, hj Lieutenant James Clark Ross, R.N., F.L.S.," pp. 91-120. He says tliat in 

 his " brief notice of the Marine Invertebrate Animals brought home by the late Expedition, 

 the generic arrangement of M. Le Chevalier de Lamarck {Histoire Naturelle ties Animaux 

 sans vertebres) has been followed in every instance." On the Amphipoda his notes are as 

 follows : — 

 "10. Caprella scolopendroides. Caprella scolopendroides. Lam. v. p. 174. Gammarus 

 quadrilobatus. Zool. Dan. iii. p. 58, Plate 114, fig. 11, 12, Female (young?) Squilla 

 quadrilobata. Zool. Dan. ii. p. 21, Plate 56, fig. 4, 5, 6, Male (young?) Squilla lobata. 

 Fabr. Faun. Grosnl. p. 248, No. 225. "Was found abundantly at Port Bowen, but 

 considerably larger than those from which Miiller's drawings were * taken, and nearly as 

 large as the magnified figures. They also differ in having a great number of small spines 

 along the back, which, however, were not observable on the young ones found attached to 

 the antennae of the females. They agreed in all other respects. I have therefore considered 

 them to be of the same species, as it is probable that Miiller's drawings were taken from the 

 young. 

 "11. Cyamus ceti. Cyamus ceti. Lam. v. p. 176. Oniscus ceti. Fabr. Fauna Gh-oenl. p. 253, 

 No. 230. Zool. Dan. iii. p. 69, Plate 119, fig. 13-17. Found on a young whale, which 

 was killed in June 1 825, near Port Bowen. 

 " 12. Gammabus Sabini. Gammarus Sabini. Leach, in Boss's Yoijarje, 8vo ii. p. 178. Suiyj). to 

 Parry's First Voyage, p. ccxxxii. Plate i. fig. 8-11. Found on the ice at Port Bowen, but 

 not very abundantly. 

 " 13. Gammarus loricatus. Gammarus loricatus. Bupp. to Parry's First Voyage, p. ccxxsi. Plate i. 

 fig. 7. In the figure above referred to, each pair of antennae appear to be placed on a 

 peduncle, which is not tlie case. They were found in considerable numbers on the ice in 

 Port Bowen. 

 " 11. Gaisimarus boreus. Gammarus boreus. Sujq). to Parry's First Voyage, p. ccxxix. The speci- 

 mens which I possess differ from Captain Sabine's description in having the superior 

 antennje as long as the head and six first segments of the body, and the antennae, legs, and 

 tail being fringed with most beautifully fine cilife, particularly the plates of the tail. The 

 fifth, sixth, and seventh pair of legs increase successively in length, the fifth pair being the 

 smallest. In all other respects my specimens correspond exactly with his description. 

 " 15. Talitrus nugax. Gammarus nugax. Stqipi. to Pairy's First Voyage, p. ccxxix. Cancer 

 nugax. Phipp's Voyage, Plate xii. fig. 3. By far the most numerous of the Crustacea 

 inhabiting the Arctic, Seas. The superior antennae are shorter than the inferior, which, 

 acx;ording to the arrangement followed in this notice, separates it from the genus 

 Gammarus, where it has been inadvertently placed. 

 " 16. Talitrus Edvardsii. Talitrus Edwardsii. Supp. to Parry's First Voyage, p. ccxxxiii. 

 Plate ii. fig. 1-4. "Was found on the ice at Port Bowen in great numbers. The plate and 

 description above referred to are very exact."
