The presence or absence of a j^ellowish lateral stripe, used as a 

 distinguishing character to separate glutinosus from monochrous, 

 seems to be an unsatisfactory character. In a series of three speci- 

 mens, Nos. 70670-2 from Kepahiang, Sumatra, the proportions of 

 the head and the dentition show the three to be true monochrous; one 

 of them, however, has a light lateral band along the side, while the 

 other two have no trace of such a band. Another series of four 

 specimens, Nos. 70666-9 fx'om Kaba Wetan, Sumatra, are monochrous 

 without any lateral stripe. A single specimen from North Pagi 

 Island, near Sumatra, No. 31701, has the head proportions and the 

 dentition of monochrous but has a very distinct yellow stripe down the 

 sides. While this stripe may thus be present or absent in monochrous, 

 it is constantly present in the fourteen specimens of glutinosus which 

 I have examined — 2 from Ceylon, Nos. 5895 and 58751, as well as the 

 12 from Siam listed above. The adult female, No. 70029, measures 

 312 mm. in length and is distended with about 50 eggs, which measure 

 betv/een 6 and 7 mm. in diameter. No. 76138 was found under a 

 decaying log in deep jungle.

76089 (S3906) Bung Borapet Aug. 7, 1928. 



[This species is common throughout Central Siam and in certain 

 localities abundant. The place where this young was caught, Bung 

 Borapet, formerly had more than at present. The Minister of 

 Agriculture and the Director-General of the Royal Irrigation Depart- 

 ment, both very familiar with this extensive lake-swamp, report large 

 crocodiles as having been taken here in the past, and both know of a 

 skull 1 m. long from a specimen about 7 m. long. The usual size, 

 however, is much smaller. Four crocodile eggs from this swamp on 

 August 8, 1928 measured 8.7 by 5.3 cm.; 8.5 by 5.4 cm.; 8.2 by 5.2
