220 LETTER FROM DR. J. ANDERSON. [Apr. 28, 
Mr. Sclater had already read before the Society his notes on these 
two interesting birds (see anted, p. 162). 
3. Four young Hornbills, which had been obtained by Mr. William 
Jamrach during his recent visit to Malacca and Sumatra, and ap- 
peared to be all young birds of the last breeding-season. ‘Two of 
these Mr. Sclater had provisionally determined as being a male and 
a female of the Plait-billed Hornbill (Buceros plicatus), although it 
appeared possible that the smaller female bird obtained at Malacca 
might be referable to the nearly allied species Buceros subrujicollis 
of Blyth, if, indeed, this were really to be considered distinct from 
B. plicatus. The third Hornbill, from Sumatra, appeared undoubt- 
edly referable to the female of Buceros gracilis (Temm. Pl. Col. 
535); the fourth to Buceros bicornis. 
4. Four Burrowing Owls (Pholeoptynx cunicularia), presented by 
George Wilks, Esq., C.M.Z.S., of Buenos Ayres, and received 
March 19th, being the only specimens of this interesting species 
ever received, except the one previously presented by Mr. Wilks in 
1868 (cf. P. Z. S. 1868, p. 261). 
5. A Wood-loving Antelope (Cephalophus sylvicultrix), purchased 
of a dealer March 24th, and believed to be the first specimen of this 
beautiful Antelope, which was formerly living in the Knowsley Me- 
nagerie, ever received by the Society. 

Dr. E. Hamilton communicated the following extract from a letter 
lately received from his nephew, Capt. Francis Hamilton, of the 21st 
Regt., commanding detachment at Port Blair, Andaman Islands :— 
“All of us here have been much amused by the account of the so- 
called ‘Andaman Monkey’ (Macacus andamanensis) lately received 
by the Zoological Society*. But in point of fact there are no Mon- 
keys indigenous to the Andaman Islands. One of the superintendents 
brought some Monkeys to this island (Ross), which got loose; and 
‘Andaman Jenny’ is one of them. There are three others still left ; 
they live among the commissariat sheds. There are two old ones 
and one young. They were brought from the mainland of Burmah.” 

The following extract was read from a letter addressed to the 
Secretary by Dr. J. Anderson, F.Z.S., dated Indian Museum, Cal- 
cutta, 15th March, 1870 :— 
‘«T have succeeded at last in procuring a specimen of the Irawady 
Dolphin from Bhamoo, six hundred miles from the sea. I am in- 
debted to my friend Capt. Burns for it. He found it newly stranded 
on an island opposite Bhamoo, and, according to my instructions, 
had it packed in salt and arsenic and sent down by a special boat to 
Mandalay, whence it was forwarded to me by steamer. It arrived 
in capital condition after a journey of twelve hundred miles. 
“It belongs to the genus Globiocephalus, and internally has all 
the characters of G. indicus of Blyth; but its skull has certain well- 
marked features that separate it from the latter. 
* See P. Z. 8. 1869, p. 467.
