Bal. Apoh River, base of ]\Iount Batu Song, Baram 

 district, East Sarawak. 



Type collected September 1891. 



The typical skin of this species was obtained by Mr. A. H. 

 Everett, and was recognized both by him and Mr. Charles 

 Hose (who also got a specimen at the same time and place) as 

 a different species to any previously known to them ; and this 

 opinion is quite confirmed by an examination of the Museum 

 collection of Tuj^aice. There is, however, another example of 

 it in the Museum, obtained by the Marquis G. Doria in Sara- 

 wak in 1867, and generously presented by him in 1888. 

 This specimen I had not previously closely examined, but had 

 supposed it to be an old individual of T. minor -^ it ju'oves on 

 comparison, however, to be quite similar to the example 

 collected by Mr. Everett. 



Although Avithout any conspicuous or specially charac- 

 teristic colours or markings, T. gracilis is readily distinguish- 

 able both by its size (in which it is just intermediate between 

 two groups of species) and by its coloration, the only species 

 resembling it at all in this respect being the much smaller 

 and sharper-nosed T. minor and the equally larger T. Belan- 

 geri of Burma and the Malay Peninsula.

[Plate II.] 



While working at the comparative morphology of the Galeo- 

 didaij I have found it necessary to make a careful examination 

 of the coxal glands of Scorjno^ for purposes of comparison. 

 Although these glands, through the researches of Laukester * 

 and Sturany t, f^i'e already fairly well known, some points 

 Avere left uncertain and vague — e. g., the nature of the " medul- 

 lary substance," and the question whether in adults the 

 glands opened to the exterior. This paper embodies the 

 definite results which I have obtained on these two interesting: 

 points.
