 Asiatic Society of Bengal, May 3. — Contributions to 

 Oriental herpetology, iii., notes on the Oriental lizards in 

 the Indian Museum (part ii.), Lacertidse, Scincida;, and 

 DibamidEe : Dr. N. Annandale. Three new Indian 

 skinks are described, and four imperfectly diagnosed species 

 re-described, while one, Lygosoma pulchelltim, is added to 

 the fauna of Burma. Notes on other examples of the 

 family and of the Lacertidas are given, based on the late 

 Dr. J. Anderson's collection from N.W. Asia and the late 

 Prof. J. Wood-Mason's from Sinkip Island and Malaya, as 

 well as the extensive Indian, Burmese, and Persian collec- 

 tions in the museum. A revised list of the species recorded 

 from India, Burma, and Ceylon is appended, with their 

 distribution within these limits. — Materials for a flora of 

 the Malayan Peninsula, No. 16 : Sir G. King and J. S. 

 Gamble. The present contribution to these materials con- 

 tains the account of the genus Psychotria required to 

 conclude the joint account by the authors of the natural 

 order Rubiaceffi commenced in part xiv. and continued 

 in part xv. of this series. This account of Psychotria 

 comprises descriptions of 26 completely represented and 

 3 imperfectly known species; of these, 11 species are new 

 to science. In addition, this fasciculus contains accounts, 

 for which the authors are jointly responsible, of several 

 natural orders.
