to the median vertical entosclerite ; nor of the presence of a post- 

 cerebral sucker in the foregut, woi-ked by lateral muscles attached 

 to the anterior border of the entosternite and by a dorsal muscle 

 extending to the underside of the carapace. Nor is the forwai'd 

 extension of the stomach on each side of this ascending muscle 

 and the descending aoi'ta to foi-m a channel, thi'ough which arise 

 also the two obliquely directed tendons of the entosternite, men- 

 tioned. Since these structures are not represented in the figures, 

 it is permissible to suppose they were overlooked.

 Malay Peninsula. By A. L. Butler, F'.Z.S., Super-

[Received June 9, 1902.] 



The papeis by Captain Stanley S Flower on the Reptiles and 

 Batrachians of the Malay Peninsula, published in this Society's 

 'Proceedings' during 1896 and 1899, have been so valuable to 

 local workeis, that it may be useful to bring the list of Bati'achians 

 of the Peninsula up to date by enumerating the species obtained for 

 the fii'st time fi-om that region since the appearance of Captain 

 Flower's second paper. 



In that list (P. Z. S. 1899, pp. 885 et seq.) 45 species of 

 Batrachian s are recorded from the Malay Peninsula, including 

 Megcdophrys niontana Kuhl, mentioned somewhat doubtfully in a 

 note, but since obtained again by the " Skeat Expedition," and 

 two species, Rana jerboa Gthr., and Nectes subasper Tschudi, 

 mentioned in the Addenda. 



To bring the list up to date, the following 13 species have now 

 to be added, carrying the total number up to 58. 



Four of these species, Rana livida, Rana dorice, Rhacophorus 

 bimaculatics, and Leptobrachium pelodytoides, have not been 

 hitherto recorded from the Peninsula.
