are particularly graceful, that of Hirundo domicola [juvanica, 

 Sparrm.) may be especially mentioned. 



As a record of the fact that Chelidon urbica 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 Reichcnbach, 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, "I carefully 

 compared a specimen I had shot at Darjeeling, August 8, 

 184^8, 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 diff'erences 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, Sliarpe, 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 Bucerolidce 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
