 175. Podilymbus podiceps (Liun.)- 



Cobjmhus Podii-rps Linnaeus, Syst. Nat. x. p. 136 (1758 : ex Catesby. — Carolina). 



A single ? from Caroni Swamp, February. 



170. Rallus longirostris longirostris (BoiW.). 



Rallus loiigirodrh Boddaert, Tabl. I'l. cnl. p. 52 (1783 : ex Daubenton, PI. eiil. 840— Cayenne). 



6 c?t? ? ?, from Caroni and Caroni Swamp, March and April. 



Unfortunately there are no Cayenne skins available for comparison. 



Several specimens from Western Ecuador, collected in February and September, 

 differ at a glance by their much paler, pnre olive-grey upper parts, without any 

 trace of the brownisli tint to be seen in the Trinidad series. They agree well with 

 Taczanowski's description of R. ci/percti* which therefore has to stand as a distinct 

 subspecies. I am not so confident as to the distinctness of R. I. crassirostriti Lawr. 

 of Eastern Brazil, for one specimen from S. Paulo does not show the characters 

 assigned to this form by Mr. Sliarpe, but a good series may prove it to be another 

 recognisable race. The distribution of the three forms, then, would be as follows : 



1. R. longirostris longirostris (Bodd.). 

 Cayenne, British Guiana, Trinidad. 



2. R. lonijirostris crassiro.stris Lawr. 



Eastern Brazil : Bahia, Pernambuco, S. Paulo : Iguape (spec, in Mus. Tring). 



3. R. longirostris ajpereti Tacz. 



West Ecuador : Vacqueria (Mus. Tring) ; N.AV. Peru : Tumbez (Stolzmanu). 



177. Limnopardalus maculatus (Bodd.). 



Rallus maculatus Boddaert, Tail. PI. ait. p. 48 (1783 : ex Daubenton, PI. oil. 775 — Cayenne). 



1 c? from Caroni, April, and another c? from Caroni Swamp, March. 

 Identical with specimens from Surinam and British Guiana. 



178. Aramides axillaris Lawr. 



Aramkles nxilhiria Lawrence, Proc. Pintail. ^Irail. 1803. p. 107 (Baranciuillu, North Colombia). 



1 (?, ~ ? ?, from Caroni, May ; and 1 ? juv. from Chaguaramas, January. 



The adults agree with another old male from Merida, Venezuela, in every 

 respect; but I have not been able to compare tojiotypical skins from Northern 

 Colombia. 



The sexes of this si)ecies do not differ in size or in colour. 



179. Aramides cajanea (P. L. S. Miill.). 



Fulka cajaiiea P. L. S. MuUer, Niitur.ii/sl. Sujijd. (177C) p. 110 (ex Daubenton, PI. int. 352 — 

 Cayenne). 



1 c? ad. from Caroni Swamj), March. In addition to it, the Tring Museum 

 possesses an adult ? from Savannah Grande, collected in February by Ur. Percy 

 llendall. 



These specimens agree very well with others from Surinam and British Guiana.
