Mr. H. A. Baylis on the 



of smaller papillae — one (fig. 2, /) just in front of, and 

 slightly ventral to, the large paranal pair, and another 

 (fig. 2, 4) in a similar position on the body, between the 

 paranals and the most anterior of the large postanals. There 

 are thus, in all, eight pairs of papillae, four pairs being post- 

 anal, one paranal, and three preanal. The first postanal 

 papillae (nearest to the tip of the tail) are very small, laterally

placed, and simple in structure. The second and third post- 

 anal, the paranal, and the second and third preanal papillse 

 on each side are very laterally placed, and are of a peculiar 

 and characteristic shape. They are elongate, finger-like 

 papillse, having a large swelling at about the middle of their 

 length, beyond which they again suddenly become narrow 

 and tapering, before coming to the surface of the cuticle.
