The last four insects belong to the genus Hathlia of De Jean. I 



am doubtful if the characters are yet published, and of course if they 



are not, the name in future may be changed by the describer. 



Having finished the Longicornes, I leave the remaining species 

 from Port Essington for a continuation of the present paper. 



MICROSCOPICAL SOCIETY OF LONDON. 



At a meeting of the Microscopical Society held April 27th, J. S. 

 Bowerbank, Esq., in the Chair, a paper was read by G. Busk, Esq., 

 entitled, " Observations on some Infusoria contained in water from 

 Africa." The water was procured from two localities, and contained 

 thirteen species of Infusoria, all of which, except three species, were 

 common in ordinary water ; the other three, which were of the ge- 

 nus Eunotia, were precisely similar to those discovered by Ehrenberg 

 as fossils in the Bergmehl of Sweden ; but lately he has detected 

 them in the recent state in earth from the neighbourhood of Labrador; 

 thus having tw'o localities of very different conditions as to climate 

 for the same species of Infusoria, which the author states would tend 

 to prove that no certaint}^ as to climate could be deduced from the 

 occurrence of fossil Infusoria. 



Another paper was also read by the same author, " On the young 

 of a species of Ixodes from Brazil." These insects, a short account 

 of which was given at the last meeting, were sent from Rio Janeiro 

 in a letter, and were still alive, although upwards of sixty days had 

 been spent on the passage over ; they are called by the natives Ca- 

 rapato, and are highly injurious to cattle. The author described mi- 

 nutely their suctorial apparatus and their general organization, and 

 concluded that they were gifted with extraordinary powers of vitality, 

 and imbibe their food through two suctorial tubes contained in the 

 mandibles. 



The Secretary read a letter from Dr. Southby of Bulford House*, 

 near Amesbury, Wilts, which had been handed to him by Mr. R. 

 Taylor ; it contained three different samples of disintegrated chalk 

 from Salisbury Plain ; portions of each had been given to some mem^
