40 NOTES ON MILLIPEDES. 



5. Ilupoctonus fornwsus (Butler). 



This species found iu Burma and on Owen's Island, Mergui, 

 (Pocock, Linn. Soc. Jour. Zoology, Vol. xxxvi, p. 31 G ); is pro- 

 bably the same as that recorded from Penang as Tlieltrphomis 

 angustus, Lucas by Stoliczka, J. A. S. B. Vol. xlii, Part 2, 1873, 

 p. 134. 



Sub-order Amblypygi (Tailless Pedipalps). 

 Family Tarantulidce. 



6. Tarantula j^ipsoni (Pocock) Phipson's Tarantula. 



This species is named after the able Honorary Secretary of 

 the Bombay Natural History Society. The genus Tarantula 

 has also been called Phrynus and Phrynichus. 



At Chantaboon in January 1898 I found fifteen individuals 

 of this species on one small hill, by turning over some piles of logs ; 

 they can run very swiftly, and rapidly efface themselves from 

 view by going into crevices ; but usually, like scorpions, they 

 seem to seek concealment by squatting quite still among their 

 natural surroundings. Daylight seems to confuse them, and 

 when caught they move their pincers wildly about in a most 

 aimless manner.

 An animal allied to Phipson's Tarantula inhabits the Batu

 1898 but failed to catch it.
