356 On the late Colonel TickelVs MS. “Illustrations 
are particularly graceful, that of Hirundo domicola (javanica, 
Sparrm.) may be especially mentioned. 
As a record of the fact that Chelidon urhica occurs in Te¬ 
nasserim, an example there obtained, is figured. Cotyle con- 
color and C. rupestris are taken out of Boie's genus and 
formed into a separate genus, for which the title of Krim- 
nochelidon is proposed—a generic division already anticipated 
by Reichenbach, who entitled it Ptyonoprogne. 
The genus Dendrochelidon (Macropteryx ) is retained among 
the true Swallows (and not, as by most writers, among the 
Swifts). 
Seven species of Swifts are well represented by as many 
drawings. Among these are Acanthylis caudacuta from Dar¬ 
jeeling, and A. sylvatica , from the type specimen, killed by 
Colonel Tickell at Chilpil, Singbhoom, Nov. 30, 1835. A 
very good plate shows Collocalia nidifica ( francica , Gm.) 
breeding on rocks near Akyab, Arracan, and a male bird in 
the act of flying. Colonel Tickell remarks, “1 carefully 
compared a specimen I had shot at Darjeeling, August 8, 
1848, with a pair brought to me in Akyab, Jan. 9, 1852, and 
found them precisely similar in plumage, and in dimensions 
also, within a minute fraction.” The dimensions are then 
stated; and the differences are trifling. Interesting facts 
concerning this species are related in the letterpress. A 
good account and plate is given of Cypselus vittatus ( pacificus\ 
as observed in Tenasserim. 
The Bee-eaters and Rollers, which are nearly all figured, 
are followed by the Kingfishers—the first plate representing 
the Burman Pelargopsis burmanicus, Sharpe, under the name 
of Halcyon leucocephalus , Linn., from a Tenasserim example, 
and the next the Indian form, with the correct title, H. gu - 
rial, Pearson. 
Six species of Bucerotida are depicted, and first B. bicornis 
£, about to feed the female on the nest, immured in the 
hole of a tree. A detailed account of the breeding of this 
bird*, and outlines showing the progressive growth of the 
* This account is published in Colonel Tickell’s paper “ on the Horn- 
bills of India and Burma (Ibis, 1864, p. 178).
