36 THE ZOOLOGIST. 
the Acanthopterygian Lates, the Siluroid family Ariine”and others, have 
been included amongst the freshwater fauna by Dr Giinther; whereas 
freshwater genera such as Ambassis, several genera of the Gobies, Sicydiwm, 
Gobius, Eleoteris, &c., have been omitted by Dr. Giinther from the fresh- 
water fauna of India. Thus Dr. Day attempts to show that there may be 
less affinity between the African and Indian regions, so far as freshwater 
fishes are concerned, than there is between his restricted Indian region and 
that of the Malay Archipelago. He adds that, of eighty-seven genera found 
in India, Ceylon, and Burmah, fourteen extend to Africa and but forty-four 
to the Malay Archipelago; whereas out of 369 species only four extend to 
Africa and twenty-nine to the Malay Archipelago. 
“On Heterolepidotus grandis, a fossil fish from the Lias,” was the title 
of a paper by James W. Davis. The author describes the specialities of this 
form, and remarks that the genus was instituted by Sir Philip Egerton 
for certain fish closely related to Lepidotus, but differing in their dentition 
and scaly armature. The H. grandis has interest, among other things, in 
the attachment of the dorsal and anal fins with the series of well- 
developed interspinous bones, in the peculiar arrangement of ‘the articular 
apparatus of the pectoral fins, and in the heterocercal form of the tail.—

The Secretary read a report on the additions that had been made to 
the Society’s Menagerie during the month of October, 1884, and called 
attention to a specimen of a Black-necked Coly, Colius nigricollis, pur- 
chased October 20th, being the first example of this species received alive 
by the Society. 
A communication was read by Mr. J. G. F. Riedel, containing 
comments on certain passages in Mr. H. O. Forbes’s paper on Timor-Laut 
birds, read before the Society on the 17th June, 1884. 
A communication was read from Mr. H. Pryer, giving an account of a 
recent visit to the Edible-Bird’s-nest Caves of British North Borneo, In 
illustration of this paper, Mr. Pryer sent specimens of the Swift, Collocalia 
j fuciphaga, of its nest and eggs, of the Alga on which the bird is supposed 
to feed, and of the Bat which inhabits the same caves. 
Mr. Sclater read an account of some skins of Mammals from Somali- 
land, which belonged apparently to five species. Amongst these was an 
apparently new form of Wild Ass, which was proposed to be called Hquus 
asinus somalicus. 
Mr. F. Ii. Beddard read a paper on the anatomy of the Umbrette,
