1892.] Address. 67 



pleto this rough sketch of Dr. Alcock's work during 1891 by referring 

 to a paper contributed by him in March to the Proceedings of the 

 Zoological Society of London, " On a Viviparous Bathybial Fish from the 

 Bay of Bengal, Saccogaster maculata," in which the embryo is developed 

 while still in the oviduct. The male of this species is provided with a 

 distinct copulatory organ, but there does not appear to be any special 

 modification of the oviduct in the female. 



In the December Bulletin of the Microscopical Society of Calcutta, I 

 find an interesting paper by Mr. Wood-Mason on Clathrulina elegans, 

 Cienk., a pretty Protozoan, a specimen of which was discovered in the 

 General's Tank by Mr. W. J Simmons, an active member of the Micro- 

 scopical Society. 



Outside this Presidency Mr. Alfred Gibbs Bourne, lecturer on 

 biology in the Madras University, has done some good work dur- 

 ing the past year, contributing papers to the Quarterly Journal of 

 Microscopical Science on Naidiform Oligochceta ; on Megascolex ceruleus, 

 Tempi., found in Ceylon ; and on Pelomyxa viridis, a new species of 

 Bhizopod discovered in a tank near the Presidency College, Madras. Of 

 Mr. Bourne's papers the most important one is that on the Naidiform 

 Oligochceta. 



The file of the Journal of the Bombay Natural History Society shows 

 that its members have not been idle during 1891. Lieut. Barnes, f. z. s., 

 continues his notes on " Nesting in Western India," and his letterpress 

 is accompanied by very trustworthy coloured drawings of most of the 

 eggs collected. Mr. A. W. Morris, F. z. s., contributes to the Journal 

 an interesting paper on "Abnormal Horns of the Indian Antelope," with 

 a plate. 



Turning to another branch of Natural Science I must not forget to 

 mention that Col. Waterhouse has been continuing his observations on 

 electro-chemical reversals of photographic plates with Thio-carbomides, 

 and has published notes in the Proceedings of this Society and in the 

 Journal of the Photographic Society of India. 



The fascinating study of Indian Entomology has attracted a large 

 number of workers during the past year, and 

 nro gy- several interesting communications upon the 



subject have been read before this Society. 



Among the publications of the year may be noticed : — 



(1.) Mr. Hampson's elaborate monograph on the moths of the 

 Nilgiris, published by the Trustees of the British Museum. In this 

 work Mr. Hampson describes and figures about three hundred neAv 

 species, the classification being chiefly based upon the Indian Museum 

 Catalogue of Moths. The figures are coloured, and the work will be a 

 most valuable aid in the identification of species,
