flab. Apoh River, base of Mount 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 Zupaie. '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 7. m¢nor; it proves on 
comparison, however, to be quite similar to the example 
collected by Mr. Everett. 
Although without any conspicuous or specially charac- 
teristic colours or markings, 7’. 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 7. m¢nor and the equally larger 7. Belan- 
gert of Burma and the Malay Peninsula.

[Plate II.] 
WHILE working at the comparative morphology of the Galeo- 
did, I have found it necessary to make a careful examination 
of the coxal glands of Scorpio, for purposes of comparison. 
Although these glands, through the researches of Lankester * 
and Sturany {, are already fairly well known, some points 
were 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.
