 Fresh specimens are black above, with numerous spots on top of head, 

 the superciliary edges, both lips, numerous narrow cross bands and the whole 

 of the lower side bright golden yellow with a greenish reflection during life ; 

 the stripe from the nostril to below the eye, continuing above the angle of 

 the mouth, one stripe on each side along the margins of the labials, and all 

 the other light spots on the back, but particularly at the sides, are sea-green, 

 more or less tinged with yellow.

[With plate XII.] 



Towards the end of last year, a monograph of the genus Thelyplionus 

 appeared in the September number of the Annals and Magazine of Natural 

 Histor3^ The author of the paper, Mr. A. G. Butler, seems to have sifted 

 well the materials of the national collection in the British Museum, but 

 whether he has succeeded in his determinations of known, described and 

 figured, species, is a question on which I may be permitted to say a few 

 words. I will not unnecessarily transgress the field of my observations, and 

 will chiefly confine my remarks to the Indian representatives of the genus. 



I had for some little time devoted attention to these Arachnoids, and 

 it has been my intention to publish a detailed monograph of the Indian 

 TJielyplioni, together with an account of their anatomy,* notes on their 

 habits, propagation, development, etc., all points about which our present 

 knowledge is as yet very imperfect. Unfortunately, I have just at the 

 present neither the time nor the materials which would justify me to 

 treat satisfactorily with this subject, and I must leave it, therefore, for a 

 subsequent communication. One of the chief objects of the accompanying 

 notes is to draw the attention to certain discrepancies, or perhaps insufficien- 

 cies, in Mr. Butler's determinations of a few of the Indian Thelyphoni. 



the coloration is somewhat similar to that of F. alternans, the occipitals are much 

 longer than the vertical, and there is only one anterior frontal, this, however, is 

 also said to exist in an old specimen of SieboZdi from Siam. Still I am not certain 

 that Giinther's suggested identity of the two snakes will be confirmed. 



Jan does not acknowledge the distinctness of Ferania from Hipsirhina, and if F. 

 Sieholdi has occasionally only one anterior frontal, the principal reason for keeping 

 the two genera as distinct no doubt looses its validity. 



* As compared with that of the Scorpions.
