 On a New Species of Nejira. 



By Rev. J. E. Tenison-Woods, F.G-.S., &c, Corr. Mem. Linn. 



Soc, N. S. W. 



The following species of the rather uncommon genus Necera 



was dredged up a few days ago, by Dr. James Cox, in Port 



Jackson, at a depth of 16 fathoms. Only three or four specimens 



were obtained, in company with a number of broken and dead 



valves of Trigonia Strangei. It is worthy of remark that the 



number of Necera properly so called is far less numerous than is 



commonly imagined. Many shells formerly belonging to this 



genus have been distributed among other tribes. See A. Adams 



on the Necera of Japan, Ann. Nat. Hist, 1864, p. 206. Two 



species were formerly attributed to Australia, N. fragilis, A. Adams, 



and N. rugata, the former from Moreton Bay, the latter Port 



Jackson. N. fragilis is now removed to the genus Theora. 



N. rugatais a very small species. The following is the diagnosis.
