14. Diplopelma bunguranum sp. nov. 



Similar in habit to Diploiielimi oriinliiM. Head rather small, with angular 

 canthus rostralis and with the snout somewhat projecting beyond the mouth, and 

 rather longer than the eye. Interorhital space broader than the u]iper eyelid. Mouth 

 narrow; tongue large, subelliptical, not notched behind. Tympanum well formed, 

 but covered by the skin. The third finger projects much beyond the three others, 

 which are short, the fourth particularly so. Toes short, very slightly webbed, the 

 third a little longer than the fifth, the first very short. No disks. Metatarsal 

 tubercles very indistinct. If the hindlimb is carried forwards, the tibio-tarsal 

 articulation does not reach the eye. Skin on the back minutely gra'.iular, nearly 

 smooth ; sides and lower parts of the body with larger tubercles. 



Back dark purplish brown. A reddish rose-coloured band borders the upjier 

 outline of the snout in its entire circumference, and runs above the eye and tympanum 

 to the side of the bodv, where it widens and merges into the red colour of the hind-legs ; 

 on the loins it encloses an o\.al black spot. The sides of the head and the throat are 

 black, which colour extends over a greater or lesser portion of the abdomen, the 

 remainder of the abdomen being of a yellowish rose-colour. Small pointed tubercles 

 of an intense yellow are scattered on the sides and lower })arts; sometimes two on the 

 chest are particularly conspicuous and symmeti'ically placed. Hind-legs rose-coloured ; 

 thighs with round yellow spots; calves with one brownish baud across the middle, 

 sometimes with a second nearer to the knee-joint.

To judge from the number of specimens in (he collection, this lovely I'Vog mu.st
