genus. “In this genus there have hitherto been only two recognized 
species—the European Martin ( C . urbica, L.) and the Cashmere 
Martin ( C. cashmiriensis , Gould), the Nipal Martin ( Delichon 
nipalensis, Moore) being of an intermediate form between the 
true Martins and the Sand-Martins. The Cashmere Martin is 
at once distinguishable from its English congener by its much 
smaller size, by its deep-brown axillaries, and by its shorter and 
much less furcate tail, as also by the browner colour of its upper 
parts. That it is a good species there can be no doubt. Mr. 
Whiteley's specimen, in the steel-blue colour of the upper parts, 
assimilates to the European species, but differs from it strikingly 
in its smaller size, in its much less emarginate tail, in its deep- 
brown axillaries, and in having the whole of the upper tail- 
coverts pure white instead of steel-black at the tips. Its breast, 
moreover, shows no sign of the partial brown band of the House- 
Martin. Now, strange enough Capt. Blakiston has brought from 
Hakodadi, Japan, another Martin, which, on the other hand, 
resembles C. cashmiriensis in its proportions, in the colour of the 
back, and in the almost even tail, but differs from it in having a 
black chin, black instead of brown axillaries, and in having the 
ends of the lower tail-coverts broadly tipped with black. Capt. 
Blakiston assures me that his specimen is a mature male, shot 
in July.” 
The species of the genus Chelidon will therefore now stand as 
follows :— 
(1.) C. urbica , L. 
Hab . In Europa. 
(2.) C. cashmiriensis , Gould. 
Minor prsecedente : cauda breviore, subfurcata; partibus superi- 
oribus atris, vix purpureo-splendentibus: axillaribus fuscis. 
Hab. In Cashmiria. 
(3.) C. blakistoni, n. sp. 
Simillima C. cashmiriensi , sed mento, axillaribus et tectricum 
infracaudalium apicibus atro-fuscis: gula nivea: subtus 
fuscescens, rachidibus plumarum multarum, prsesertim crissi 
et etiam uropygii, fuscis. 
Hab. In Japonic ins. Yesso.
