34 NOTES ON MILLIPEDES. 



3. Isometrus maculatus (De Geer). 



T/his is another small yellowish brown scorpion ; it has 

 been found in Spain, Africa, India, Ceylon, Malay Peninsula, 

 Siam, Hongkong", Java, Timor, Mauritius, Madagascar, Sandwich 

 Islands, West Indies and South America. I caught two speci- 

 mens in the Officer's Mess, Sepoy Lines, Penang ; one in the 

 Officer's Mess, Tanglin, Singapore ; one in Raffles Hotel, Singa- 

 pore ; and two in Bakar Bata House, Kedah. I was given two 

 specimens in Bangkok said to have been caught there, but I 

 never myself came across it alive in that city. This species, 

 when suddenly found, will often lie still as if feigning to be dead, 

 till touched, when it tries to run away. 

 Sexes. 



" In / maculatus the tail and pincers of the male are very 

 long and thin as compared with the female." Pocock.

4. Chcerilus agilis, Pocock. The Agile Scorpion. 



This species was discovered by Mr. H. N. Ridley at the 

 Batu Caves, Selangor, and described by Mr. R. J. Pocock (Annals 

 + Mag. Nat. Hist. Series vii, vol. 'hi, No. 17, May 1899, p.

 variegated. Pectinal teeth 4. Length 50 mm. 



5. Chcerilus rectimanus, Pocock. The Straight-handed Scorpion. 

 Mr. H. N. Ridley discovered this species in Singapore, and 



it has been described by Pocock (loc. cit. supra, p. 418). 



The general colour is ferruginous, variegated with black. 



Pectinal teeth 3 (?). Length 24 mm. 



Other species of this genus will probably be eventually found 

 in the Malay Peninsula. 



G. Palamnceus oatesii, Pocock. Oates' Scorpion. 



This large species, known as " Kala " by the Kedah Malays, 

 is often identified as Palamnceus spinifer (Hempr. 4- Ehrenberg). 

 L. Wray, jun., J. S. B. R. A. S. No. 21, 1890, p. 148, mentions 

 "a large dark metallic green scorpion (Buthus spiniger)" in 

 Batang Padang, Perak ; he probably refers to this species. 



I obtained one specimen from near Jenan, Kedah ; four 

 from Kulim, Kedah ; two from Penang Hill (one at 2500 feet
