Trinidad throngh the Paria peuiiisulu. Quite si nnniliei- of forms characteristic of 

 the north coast of Venezuela extend tlieir range into the island, and several others 

 are strictly confined to Trinidad and tlie neighbouring district of Vcneznola, viz. 

 the state of Cumanu (and sometimes the northera portion of the Orinoco delta). 

 Sucii s])ecics are tlie following : Tnrdns phaeopijtjui pliaeopi/yokles, Uampliocelus 

 jacapa magnirostris, ['hocnicothmiipis rubra, P/iact/ioniis gmj gui/, Agijrtriu 

 ckionopectus cliionopectiis, etc. 



Other siiecies show decided Guiana affinities, and are not known to occur 

 in the coast region of Venezuela. Hore belong Molothni.s iitroniti'ns, Sclateria 

 naevia, Pliaethoruis Ionguemareu$, Ceryle superciliosa miperciliosa, Trogon violaceus 

 riolaceus, llampliastos citellinus, Amazona amazonica, Coluniha rtifina rufna, Rallus 

 longirostris longirostris, etc. Thns the avifauna of Trinidad is composed of two 

 elements, Lnt the true Venezuelan forms are much in preponderance. 



Besides, there are a number of species and subspecies peculiar to tiie island of 

 Trinidad. Mr. (ihapman {l.c. p. 7) enumerates twelve species, four of which were 

 since shown to occur also on the mainland (Phelps, Ati/t 1897, p. 302). The 

 careful comparison of onr Trinidad series with the material from Cnmana* and 

 the Orinoco region f in the Tring Museum brought to light several other forms, 

 which, though nearly allied to their mainland representatives, have sufficiently 

 marked characters as to warrant subspecific separation. The following is the list 

 of these forms with their mainland representatives : 



Of these ten peculiar forms three : Dgsitkanuus affiitis undrci, Calospizu 

 mexieana vieilloti, and Celens elegans Icotaudi, are of undoubted Guianan origin ; 

 Pipile pipile finds its nearest ally in a bird inhabiting the environs of Paril, 

 while five others are of decided Venezuelan affinities, lliplranuam t. rujimentum 

 has close allies in the West Indies and in the (iuiauas, being therefore of no 

 importance for the present consideration. 



it now remains to say a few words about the relations between Trinidad and 

 Tobago. The only recent account about the birds of Tobago is Comte de Dalmas' 

 excellent paper in the Mcmoires dc la Socicfc Zoologique de France, xiii. (19U0) 



• This collection, nnmbering abont 1200 specimens, wa-s made by a Mr. Caracciolo, one of Mr. Andr6"s 

 collectors. 



t This comprises the extensive collections made by Mr. Cherrie on the Orinoco, that of Messrs. 

 Klages and Andr6 on the t'aura River, and a sm:tll collection from tJuanoco in tlic Orinoco ilelta, received 

 from Mr. Andr6.
