ZAOCYS 135 



Casto de Elera includes Conjphodon fuscus? {= Zaocys fus- 

 cus) from Borongan, Samar; also under the same genus, Conj- 

 phodon, he lists C. mucosus {=Ptyas mucosas) Linnaeus from 

 Bataan, Luzon, C. Korros (= Ptyas korras) Reinwardt from 

 Manila, and C. hexanotus {= Xenelaphis hexagonotus) Cantor 

 from the Calamianes. It is highly probable that these records 

 are erroneous.

Remarks. — The type in the British Museum is a male from 

 Luzon, collected by A. B. Meyer ; the exact locality is no longer 

 known. A specimen from Leyte is reported by Boettger.* 



The species is represented in the Bureau of Science collection 

 by the head of a specimen (Plate 13, figs. 1, 2) captured at 

 Sarai, Paete, Laguna Province, Luzon, by R. C. McGregor. 

 According to field notes the specimen measured 2.24 meters. 

 The following are the characters of the head scales : Rostral 

 narrowly visible above, one-fifth wider than high ; internasals 

 broader than long ; prefrontals very much broader than deep ; 

 frontal little longer than its distance from rostral, one-fourth 

 longer than wide, a little shorter than parietal, as long as but
