1870.] MR. R. B. SHARPE ON ETHIOPIAN HIRUNDINIDE. 303 
1817. I prefer to retain that of Vieillot, as the names of this 
author are generally recognized for Levaillant’s figures. I think 
Mr. George Robert Gray is wrong * in referring the bird called by 
Riippell O. paludibula to C. fuligula (Licht.) ; for Riippell di- 
stinctly quotes Levaillant’s plate 158. fig. 2, not fig. 1, as being the 
same species. It is evident that he has written Vieillot’s name 
from memory, and thus published it as paludibula instead of palu- 
dicola. We again writes in this way in the ‘Syst. Ubersicht,’ and 
Von Heuglin apparently copies the mistake. 
8. CoryLEe MINOR? 
Cotyle minor, Cab. Mus. Hein. Th. i. p. 49 (1850). 
Hab. North-eastern Africa (Mus. Hein.). 
According to Dr. Cabanis this Martin approaches C. riparia and 
C. palustris in form and colour, but is larger than the former and 
smaller than the latter, and differs from both in the form of the tail, 
and also in the colour of the underside, as in this species both the 
grey breast-band and white throat are wanting. The chin and throat 
down to below the breast are yellowish grey. 
I have now a specimen lying before me of what I take to be this 
species, brought from Abyssinia by Mr. Blanford, and I cannot see 
that it is really distinct from Cotyle paludicola. It appears to be 
identical with a Natal specimen of the latter in my own collection, 
with the exception of the length of the wing, which is longer in my 
Natal bird. I cannot perceive, even in the rather unsatisfactory 
diagnosis of Dr. Cabanis, any real characters whereby the species 
may be distinguished from C. palustris; but as I dislike to unite 
any species together without full evidence of their identity, I prefer 
to keep the present bird distinct, supposing that the Abyssinian 
specimen examined by me may, after all, not be the trne C. minor, 
but C. palustris, which Dr. Cabanis also had in Heine’s Museum 
from North-eastern Africa at the time he separated the former 
bird. 
The specimen lent me by Mr. Blanford was shot by him on 
Lake Ashangi, where he informs me it was rare. The measure- 
ments are as follows :— 
Whole length. Wing. Tail. Tarsus. Middle toe. 
1. C. minor(?) .. 4°5 3°9 1074 0°3 :
