7 upper labials, second forming the anterior border of tlie 

 loreal pit. Scales strongly keeled, in 23 or 25 rows. Ven- 

 trals 178-187; anal entire; subcaudals 41 ( ? ) -63 ((^), 

 partly single, partly in pairs. Tail preliensile. Yellowish 

 green above, speckled with black, with large black irregular 

 spots, some of which may form cross-bars ; the spots very 

 large on the top of the head, separated by narrow lines of 

 the ground-colour forming symmetrical markings ; a broad 

 black band on each side from the eye to the angle of the 

 mouth ; lower parts greenish yellow, speckled or spotted 

 with black ; end of tail bright yellow. 



Total length 740; tail 110 mm. 



Three specimens from Huancabamba, E. Peru, above 

 3000 feet, from the collection of Mr. E. Boettger. 



Closely allied to L. peruvianus, Blgr. ; distinguished by the 

 rounded snout without raised canthus, the presence of two 

 series of scales between the eye and the labials, and the very 

 different coloration.

 Bromeliaceffi. By Hugh Scott, M.A. (Cantab.), F.L.S.,

The fauna inhabiting the spaces between the bases of 

 leaves of Monocotyledonous plants in the tropics oft'ers for 

 investigation a fascinating field, in which that of the 

 Bromeliacese is pre-eminent in its interest. The curious 

 funnel-like form and closely fitting leaf-bases of these plants, 

 adapting them for the holding of water and oi'ganic detritus, 

 their distribution throughout the richest parts of the 

 Neotropical Region, their vast numbers of individuals and 

 frequent epiphytic habit, all lead to the expectation that 

 they may contain a rich and interesting series of animal 

 forms.
