The left foot of No. 67467 shows a peculiar malformation which I 

 have never seen before. The three outer toes are quite normal, but 

 the inner two toes are about equal in length and are grown together 

 almost to the tips. At half their length they turn sharply inwards at 

 right angles and finally point directly backwards toward the heel. 

 The other foot of this individual is normal.

Although these are all very young frogs wliich have not long com- 

 pleted their metamorphosis, they evidently are referable to this species 

 of large-headed frog which Dr. Malcolm Smith has recently described 

 from Koh Chang.

75522-3 (83507-8) Nong Ri, Nakon Nayok June 1, 1927. 



One of the most interesting finds was the discovery of this rather 

 rare species at Nong Mong, Lam Tong Lang, and Nong Ki. 



The diagonal glands on the back are plainly visible in fully half 

 of the 20 specimens. The glands always run from the left shoulder 

 toward the right hip, and are frequently emphasized by a black 

 pigment accompanying them. The age of the individual seems to 

 have nothing to do with the development of these diagonal glands, for 

 some of the largest as well as some of the smallest ones are quite 

 smooth, while some show very distinct diagonal ridges.

One adult male and three very young frogs and some tadpoles 

 belonging to this species have been collected by Dr. Hugh M. Smith 

 in Siam, but unfortunately the exact locality record did not accom- 

 pany the specimens. The adult (No. 67320) measures 33 m. in length, 

 which is exactly the same as one of Boulenger's specimens cited in
