not manifest any well marked lips. The oesophagus is \" long by about 

 ■g-i^'' wide ; and the csecal commencement of the sperm tube may, in well 

 prepared specimens, be detected lying near the junction of the oesophagus 

 and the intestine. The sperm tube measures about -^^" transversely, 

 and the intestinal canal about -yto" — both measurements being made towards 

 the middle of the body of the worm. 



mhe female is, speaking generally, about double the size of the male. 

 It is from 6" to 8" long and from -^" to ■^" across, at the widest part. 

 The mouth is simple and somewhat pointed, the width of the parasite at 

 this part averaging -^". The tail is blunt — terminating in a slightly 

 clubbed or funnel shaped enlargement ; its width at the extreme end aver- 

 ages -YT&'i but a little higher up its diameter is somewhat less- — 2"o"o '• ^^^ 

 oesophagus averages -3" in length and y|^" in width, and the intestine about 

 lYo'^- The anus terminates at a spot about y-^o" from the caudal end. 

 The genital orifice is about -^" from the mouth. For about a quarter of 

 an inch from the orifice the genital tube presents nearly the same diameter, 

 viz,, about g-io"? ^^^^^ t^iQn it rapidly widens to -ywo" ^^^ subdivides into 

 two utero-ovarian tubules, each measuring -y\o" transversely. The tubules 

 ai'e generally packed with embryos averaging -^\^" in length by ^oV ^" 

 width. Lower down, ova, in various stages of differentiation, and ero.bryos 

 are mixed together. 



The specimens examined had been for a short time in spirit ; they 

 were of a yellowish-white appearance and female specimens more numerous 

 than males. There was no marked difference as to firmness of texture 

 between them A fuller description of the minute anatomy of the parasites 

 has been prepared and is nearly ready for publication.

 5. Notes on the Singpho and Kampti country, North-Eastern Frontier. — 

 By Chas. H. Lepper, F. R. G. S., M. R. A. S. (vide Map.) 



General Walker has desired me to write a short paper on the tract of 

 country beyond our extreme North-Eastern Frontier, the tract between 

 us and China, about which so little is known, in fact I may almost say 

 about which nothing more is known than was brought to light by Wilcox 

 more than fifty years ago. Even that indomitable and admirably correct 

 explorer had to leave a strip of country between us and China totally un- 

 visited and unreported upon. Having in those days to start from a point 

 much further within our frontier than would be necessary now-a-days, he 

 and his party were tired out and at the end of their energies and supplies 

 before getting more than half-way between our present frontier and China, 

 and felt obliged to return. Since his time we have got, literally speaking,
