NILS GYLDENSTOLPE, MALAYAN BIRDS AND MAMMALS. 19 



Unlike the other long-tailed Cuckoos this is more a juiigle 

 species which generally inhabits the deepest forests, where it 

 climbs about among the dense foliage, verv seldom taking 

 to the wings. Javan and Bornean specimens agree well with 

 those from the Malay Peninsula both in size and colouration 

 of the plumage, as shown by a series in the Royal Natiiral 

 History Museum of Stockholm. 



64. Rhopodytes siimatraiius Raifles. — 1 ? ^7^ l^^^- 

 Tris: bluish white. Wing: 140 mm.; Culmen: 32 mm. 



65. Rhopodytes diardi Less. — 1 c? "A 1915. Iris: 

 brown. Wing: 128 mm.; Culmen: 25 mm. In the southern 

 portions of the Malay Peninsula this is a very common 

 species. Towards the north it is replaced by the allied 

 Rhopodytes tristis hainamis Hart.

67. Cacomaiitis menilinus >: quernlus. — 1 ? /i 1915. 

 Wing: 97 mm.; Tail: 103 mm.; Culmen: 15 mm. In the 

 Novitates Zoologicse Vol. XIX, 1912, pp. 332—335 Strese- 

 mann has given an excellent review of the Forms of Caco- 

 mantis merulinus and Cacomantis sepulcralis. He there comes 

 to the conclusion that the form of Cacomantis occurring in 

 the Malay Peninsula is intermediate between the true C. 

 ynerulinus Scop. from the islands of the Malay Archipelago 

 and C. merulinus queridus Heine from. the mainland north 

 of the Malay Peninsula. Unfortunately there are very few 

 specimens from the different localities in the collections of the 

 Royal Natural History Museum of Stockholm and I therefore 

 have accepted the name used by Stresemann. In 4 speci- 

 mens from Java the wing measures 101, 102, 103 & 104 mm. 

 respectively. 



68. Lyiicornis temiiiiiickii Gould. — 1 J" ^Vi 1915; 1 

 $ ^3/5 191*5. Iris: brown. Wing: ^ 196; 9 203 mm. This 

 fine Nightjar is very abundant in the low-lyingcountry where 

 it may generally be seen at dusk rapidly flying in search of 

 food. In the Siamese Malaya it was never met with, but 

 replaced by Lyncornis cerviniceps Gould. which has not beeii
