lateral pair on each side are very broad tind dilated on the inner side, 

 forming an entire expanded disk ; all the diverging lobes at the 

 front inner and at the hinder inner margins are obliterated and 

 covered with the callous outer surface. In the same manner the 

 anterior outer process is reduced to a short, broad, blunt, simple 

 process ; and the hinder outer one is also reduced to a short thick 

 process, bluntly divided into two lobes at the end. 



The hinder pair of anal callosities are very large and triangular, 

 nearly as broad as long. The pair are united to each other by a 

 straight central suture, so as to form a broad triangular callosity, 

 the anal and the hinder lateral bones being united by two sinuosities, 

 being the remains of the usual lobes on the marginal plates in the 

 young animal. 



The most remarkable peculiarity, because there is no indication of 

 it in the younger specimens, is that it possesses a moderate-sized 

 triangular callosity, with a curved hinder side on the middle of the 

 odd anterior sternal bone, showing an alliance in this respect to the 

 E)n)/di)ia, or Mud-Tortoises with valves over their feet, which 

 generally have an odd anterior callosity ; but I had never before seen 

 it in a tortoise with exposed hind feet and legs. 



Bryozoa of Florida. 



F. A. Smitt has published the first part of the descriptions and 

 figures of the Floridan Bryozoa, collected by Count L, F. de Pourtales, 

 in the ' Kongl. Svenska Vetenskaps Akademiens Handlingar,' 

 vol. X. 



This paper, like many others pubhshed by the Royal Swedish 

 Academy of Sciences, is entirely written in the English language, 

 and is illustrated with five very large plates, showing the various 

 changes of form that the species undergo. — J. E. Gray. 



The late Robekt M'Akdrew, Esq., F.R.S. 



We much regret having to announce the death on the 22nd inst. 

 of Mr. Robert M' Andrew, F.R.S. , at his residence, Isleworth House, 

 in the 72ud year of his age. His researches by dredging in the 

 North Atlantic from Hammerfcst to the Canary Isles, as well as in 

 the Mediterranean and GiUf of Suez, produced most important 

 additions to our knowledge of the geographical distribution of the 

 marine invertebrate fauna. He was an excellent conchologist, having 

 derived his taste for that branch of natural history about thirty years 

 ago from the lamented Edward Forbes. Mr. M'Andrew was at that 

 time engaged in commerce, but latterly devoted his ample means and 

 time to the pursuit of science. We believe he has left his extensive 

 collection of shells to the University Museum at Cambridge. His 

 contributions to this Journal were extremely valuable. — J. G. J.
