338 Mr. D. A. Bannerman on the [Ibis, 



I have not been able to trace a specimen of this Shear- 

 water from the Canarian Seas. It is moi*e than likely to 

 occur there, but would easily pass unnoticed at sea amongst 

 the countless numbers of Puffinus kuhli fortunatus, from 

 which, however, it may be easily distinguished by its distinct 

 brown cap. 



Range. The Greater Shearwater breeds on Tristan da 

 Cunlia, and probably on other islands of the southern 

 Atlantic, and ranges over the entire Atlantic Ocean from 

 Greenland and Iceland to the Falkland Islands and the Cape 

 of Good Hope. 



Family Rallid^. 



Fulica cristata *. African Crested Coot. 



Fulica cristata Gmel. Syst. Nat. 10th ed. i. pt. 2, 1789, 

 p. 704 — Type locality : Madagascar. 



Cabrera is responsible for the inclusion of this bird. It 

 figures in his list (Catalogo, p. 61) as well as Fulica atr'a, so 

 that it is obvious he was aware of two different birds. Of 

 the Crested Coot, Cabrera remarks " Esj)ecie sumamente 

 rara en Canarias, pero que suele encontrarsela en compailia 

 de la anterior" {F. atra). 



Range. The African Crested Coot inhabits Africa generally. 



Porphyrio caeruleus. Purple Gallinule. 



Fulica ccerulea Vandelli, Mem. Acad. Real. Sci. Lisboa, 

 i. 1797, p. Q7 — Type locality : Portugal. 



The Purple Gallinule has been obtained on one occasion 

 in Tenerife, where Cabrera saw a specimen which had been 

 caught there (Catalogo, p. 61). Previously to this \^Hor. 

 phyriu casius Barrere] is mentioned by Mompo [Catalogo 

 de las Aves de Tenerife, 1876, p. 256] from the Canary 

 Islands, but no great reliance can be placed on this record. 

 Neither am I inclined to include the above record of Cabrera's 

 as a genuine visitor. 



* Fulica cristata may be distinguished from Fulica atra (1) by the 

 entire absence of white tips to the inner secondaries ; (2) by having 

 knob-like excrescences at the top of the frontal shield.
