48 NILS GYLDENSTOLPE, THE SWED1SH ZOOLOGICAL EXPEDITIONS TO 3IAM. 



Mr. Thomas also gives some measurements of Cannomys minor (tom. cit. p. 31b). 

 All these measurements are somewhat different from those of the specimens in my collec- 

 tion and, as tlie colouration in these specimens also is different I think that the Bamboo- 

 Rats from the Korat plateau in Eastern Siarn ought to be separated subspecifically under 

 the name of Cannomys minor lönnbergi subsp. n. 



Diagnosis: General colouration slaty grey with a longitudinal white band on the 

 crown. From the chin down the throat a narrow white line. Tail dark brown, except 

 the utmost tip which is black. The whole tail is clothed with a few scattered hairs. Hands 

 and feet dark brown. Hindfoot (measured in skin) = 27 mm. 



Type: adult female, collected at Sakerat in Eastern Siarn, February 1912. 



Skull: Condylus to gnathion 41,1 mm. 



Zygomatic breadth 29,9 (31,1/ 



Length of nasals mesially 14,5 (15,0} 



Breadth of nasals anteriorly 5,0 ( 5,l) 



Breadth of nasals posteriorly 2,1 » ( 2,i) 



Width of bra in case above root of zygomata .... 18,1 » 18,1) 



Least interorbital width 9,5 » ( 8,8) 



Upper molnr series (alvoolar) 9,7 » (10,2) 



Lower molar series (alveolar) 10,2 » (10,o) 



Kreadth of m' on front face 3,9 ( 3,3) 



This species is named in honour of Professor Doctor Einar Lönnberg, the Director 

 of the Roval Natural Historv Museum in Stockholm. 



Nyctocleptes cinereus. McClell. 



A member of the Nyctoplectes Group as defined by Thomas (Ann. & Mag. Nat. 

 Hist. 8 ser. Vol. 16. 1915 p. 57). 



The Bamboo-Rats belonging to this Group are characterized by their large size 

 and by having the posterior nares nearly as wide as high. 



The large Burmese Bamboo-Rats are generally distributed in the bamboo-jungles 

 of Northern Siarn. They dig deep burrows in the bamboo-f orests, the roots of which 

 generally constitute their food. Their flesh is highly appreciated by some of the hill 

 tribes such as the Karens and the Kamuks. When cornered these Bamboo-Rats are very 

 savage and bite fiercely at anything put near them. The cheeks in this species are red. 

 Nyctocleptes erythrogenys as described by Anderson (P. A. S. B. 1877 p. 150) from the 

 Salween Hill träets is apparently the same species as N. cinereus McClell. and must 

 only be included among the synonym ns of that species. 



1 Measurements in parenthesis are those of another female obtained ät the same locality as the type.
