In tins same tank I have had at varions times, under the above 

 conchtions, the following rare Crustacea : — 



T/ii(t politd, for four months. 



Periiiu'la denticulata, two months : hatched Zoiis, and was itself 

 killed and partially devoured by Thia. 

 Jlippoh/lc L'ruitchii, one month. 

 H. pusiula, one month. 



Crauf/un fascia t us, three weeks: all killed by T/iia. 

 The N'aryinj:; Prawn (P. t^arians), two months. 

 Squill Prawn (P. squUla), two months. 

 Common Shrimp (t*. vulyaris), three weeks. 

 Hippulyte carians, three months. 



Most of them died merely through neglect in changing the water, 

 which I generally do not oftencr than once a month. The tank is 

 kept in a shady j)lace, and uncovered, and the animals are but seldom 

 feci, and then as often on small snails or wood-lice as anything else. 

 The sea-water for change is kept in a large bottle with a narrow neck 

 and transi)arent sides, closely corked, and sometimes, when used, 

 has beer, three months or upwards in the bottle ; so that the keeping 

 of marine animals of the crustacean group is not such a dithcult 

 task as is commonly supposed. 



The Zol'S differ from those of Cancer pagurus in having no lateral 

 or frontal spines on the cara])acc, and in having no spines at the inner 

 angle of each joint of the abdomen below. The carapace is also very 

 large ; the abdomen is divided into six rings ; the thoracic limbs are 

 three (?), the most anterior hardly to be distinguished in form from 

 the external foot-jaw of many of the Porcellauidoe. — Proc. Dubl,

EUBUCCO AURANTIICOLLIS, Sp. nOV. 



Viridis, pileo ct mento summo intense saiiguineo-rubris, torque 

 cervicali j)ostica dare Jtavicanti-viridi : cervice antica auran- 

 tia ; pectore coccineo, ventre Jlavo et viridi strigato : rostra 

 Jlavo, pedibiis nigris. 



Long, tota 5*5, ali^j 2'G, caudae 1'9. 



This beautiful species of Barbet closely resembles E. Richardsoni 

 figured in Gray and Mitchell's Genera of Birds, but may be distin- 

 guished by its light green posterior neck-band, orange and not 

 lemon-yellow throat, and deeper scarlet breast. Mr. Bates has 

 transmitted five examples from the Rio Javarri, which are all alike. 

 1l\\q Eubucco Richardsoni is from New Grenada (Bogota collections). 



The British Museum contains an example of this new species 

 collected by IlauxwcU on the Ucayah in August 1852 aud marked
