192 THE ZOOLOGIST. 
The Rev. A. H. Cooke read a paper on the position of the land-shells 
of Australia and the adjacent islands, commonly referred to the genus 
Physa, which it was shown (mainly from an examination of the radula) 
were really more nearly allied to the genus Limnea. Mr. Cooke pro- 
posed to refer those species to the genus Bulinus, established by Adanson 
in 1757. 
Mr. G. A. Boulenger read notes on some specimens of Lizards belonging 
to the Zoological Museum of Halle, which had been sent to him for 
examination. To these notes were appended revised descriptions of two 
Lizards from the Argentine Republic— Gymnodactylus horridus and 
Urostrophus scapulatus. 
A communication was read from Prof. W. N. Parker, containing an 
account of the occasional persistence of the left posterior cardinal vein 
in the Frog. This condition, abnormal in the Frog, was shown to be 
essentially normal in Protopterus. 
A communication was read from Mr. J. Douglas Ogilby, containing 
notes on some fishes new to the Australian fauna. 
Mr. Oldfield Thomas read a paper giving the description of a new 
Bornean Monkey belonging to the genus Semnopithecus, obtained by Mr. 
Charles Hose on the north-west coast of Borneo. The author proposed to 
name it Semnopithecus hoset, after its discoverer. 
April 2,1889.—Prof. Frowrr, O.B., LL.D., F.R.S., President, in the 
chair. 
The Secretary read a report on the additions that had been made to the 
Society’s Menagerie during the month of March, and called attention to a 
specimen of the Manatee, Manatus australis, purchased March 2nd, being 
the second example of this Sirenian obtained alive by the Society; to an 
oriental Phalanger, Phalanger orientalis var. breviceps, presented by Mr. 
C. M. Woodford, of Sydney ; and to a specimen of Owen’s Apteryx, Apteryx 
oweni, presented by Capt. C. A. Findlay.. 
Mr. Smith-Woodward exhibited and made remarks on a maxilla of the 
early Mesozoic Ganoid Sauwrichthys from the Rhetic formation of Aust 
Cliff, near Bristol. 
A communication was read from Mr, W. K. Parker on the osteology of 
Steatornis caripensis. The conclusion arrived at as regards the affinities 
of this isolated form of birds was that Steatornis is a waif of an ancient 
avifauna, of which all the near allies are extinct, and the Podargus of 
Australia is its nearest surviving relative. 
Mr. Oldfield Thomas read some preliminary notes on the characters 
and synonymy of the different species of Otter. The author gave a 
revised synonymy of the four species of Lutra recognised as belonging to 
the Palearctic and Indian Regions, and of the two found in the Atthiopian
