The stinging power of scorpions forms the subject of notes by 
Green, Coomaraswamy and Drieberg (Solita Zeylanica, III, pp. 197 
and 215-6, and IV, p. 33). 
Concerning the habits of Archtsometrus mucronatus and other 
Malaysian species see Flower, J. Straits R. Astatic Soc., No. 36, July

Thelyphonidae. 
The earliest mention of the habits of Indian Thelyphonidae 
appears to be by Stoliczka (J.A.S.B., XLII [II], p. 127), who 
records his own observations and those of Mr. Peal. Peal’s obser- 
vation that ‘‘the Thelyphoni are generally found underneath the 
bark of decayed wood in groups, rarely singly’’ is somewhat 
surprising. All the specimens presented by him to the Indian 
Museum are, however, Uvropfroctus assamensis, a species whose 
habits have rarely come under my observation. 
The next reference is by Wood-Mason (Pvoc. A.S.B., 1882, 
pp. 59-60).!. Observations of a similar nature to those made by 
Stoliczka and Wood-Mason are recorded by Oates (J.A.S.B., 
LVIII (II), pp. 4-5). 
Flower refers to the habits of the Siamese Thelyphonus 
schimkewttscht (J. Straits R. Astatic Soc., No. 36, July rgor, 
pp. 37-9). 
A brief note by Green on the habits of Thelyphonus sepiaris 
will be found in Spolia Zeylanica, IV, p. 181, and one by myself on 
those of Labochirus proboscideus in Spolia Zeylanica, VII, pp. 44-46, 
fig. B. 
A further contribution to the subject is made by Fischer, who 
describes the courtship dance of Thelyphonus sepiaris (J.B.N. H. 5.7, 
XX, pp. 888-9). 
The habits of Uroproctus assamensis as observed by Kemp 
during the Abor Expedition are referred to in my note on the 
Pedipalpi collected on that Expedition (Rec. Ind. Mus., VIN, 
p. 127). 
Iam now able to describe in greater detail the habits of 
several Indian species of Thelyphonidae. My earliest and most 
extensive observations were made on Labochirus proboscideus , and 
these will be described first. 
Labochirus proboscideus is not uncommon under logs of wood 
and large stones in the jungles of the Kandy district of Ceylon ; 
but it is only to be found when the ground has been aur 
! Stoliczka does not refer to the fluid of his Thelyphonids as ee as 
stated by Wood-Mason, but as not having any offensive odour. In some species 
it is violently pungent and resembles acetic acid. In others it is more like essence 
of jargonelle and, although not very pleasant, is by no means pungent—individual 
opinions would probably differ as to whether it was offensive or not. In Wood- 
Mason’s specimens the odour was ‘‘exactly like that of a highly concentrated 
essence of pears, but... . when deeply inhaled had all the characteristic smell and 
pungency of strong acetic acid.’ Compare pp. 509-510, above.
