Show 1870.] MR. R. B. SHARPE ON ETHIOPIAN HIRUNDINIDEE. 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 distinctly 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 paludicola. H e again writes in this way in the * Syst. Ubersicht,' and Von Heuglin apparently copies the mistake. 8. COTYLE 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 m e 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 m y 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 m e 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. Tbe specimen lent m e by Mr. Blanford was shot by him on Lake Ashangi, where he informs m e it was rare. The measurements are as follows :- Whole length. Wing. Tail. Tarsus. Middle toe. 1. C. minor(1) .. 4*5 3*9 17 0*3 0*4 2. C. palustris .. 4*6 4*0 2*0 0*3 0*4 Genus 6. WALDENIA. T Waldenia, Sharpe, Ibis, 1869, p. 461 W. nigrita. 1. WALDENIA NIGRITA.
