154 Miscellaneoufi. 



Echinidse and the fossil Cystidca of Von Bnch, which are fossils 

 chiefly confined to the Silurian region. Professor Loven describes 

 the animal at great length, and figures the mouth and vent ; and he 

 proi^oscs to form for it a new section of Echinodermata, for which 

 the name Palceostomata is proposed. The name Leslcla, which I 

 gave to the genns in honour of Leske, the echinodermist, had already 

 been used for a genus of mosses and for one of Diptera. Prof. Loven, 

 being adverse to the changing of my name, suggested that I should 

 give the genus another one, when he was in London ; but the sub- 

 ject was forgotten. I would therefore now propose that Leslcia 

 be changed to Palceostoma.

Additions to the Zoological Collection in the British Museum. 

 The Zoological Collection in the British Museum has received a 

 niillion of specimens since 1837, when the registration of the specimens 

 was commenced tinder the charge of the present keeper, Dr. Gray. 

 The specimens have almost all been acquired by purchase ; and they 

 have invariably been selected, primarily, to complete \he series of 

 specimens of each class, and especial trouble has been taken to 

 acquire the original type specimens from which the species have 

 been described, and, secondly, to show the geographical range of 

 each species, taking great care to prevent the collection being en- 

 cumbered with a-Hy useless duplicates. The average yearly increase 

 has been about 36,000 specimens. 



On Pteronura Sanbachii, an Otter from Surinam. 

 By Dr. J. E. Gray, E.E.S. &c. 



The British Museum has lately received a large female Otter with 

 its cub, from Surinam. It is a fresh specimen of the animal that 

 Avas described and figured many years ago in this Journal as Ptero- 

 vura Sanbachii from a young specimen in the Museum of the Eoyal 

 Institution, Liverpool, which has remained unique until the present 

 time. The sides of the tail and feet in the Liverpool specimen had 

 been artificially depressed and unduly stretched out by the preserver. 

 In the natural state the tail is rounded and only marked with a 

 rounded ridge on each side. The Surinam Otter has a hairy nose, 

 large feet with bald soles, a thick, rather depressed, tapering tail, 

 with a subcylindrical raised border on the middle of each side, which 

 is covered with hair like the rest of the tail, and a large tuft of hair
