2 feet long. In certain parts of Italy and France, this larva is 

 sold in the public markets for human consumption. 



C. Two adult parasites, Ophryocotyle bengalensis, South- 

 well and Bothriocephalus (Anchistrocephalus) polypteri (Leyd) 

 from Teleosts. The occurrence of adult forms of Cestoda is rare 

 in Teleosts Larval stages are, however, common, the adult 

 forms usually occurring in Elasmobranchs. Adult forms are 

 more common in freshwater Teleosts than in marine forms, 

 probably owing to the fact that such Teleosts are more rarely 

 devoured by their larger and more powerful brethren, in fresh- 

 water, than is the case in the sea. 



It is fortunate that, up to the present, the larva of 

 Dibothriocephalus latus (Linnaeus, 1758), Liihe, 1899 ? has not 

 been recorded from Indian fish. The adult worm measures up 

 to 10 metres and inhabits the intestine of man. In Europe, 

 the larva occurs in the pike, the ling, the p?rch, and several 

 members of the salmon family. 



III. From Amphibians. Up to the present no Cestodes 

 (either adult forms or cystic stages) have been obtained from 

 Amphibians. 



IV. From Reptiles. Only three species, comprising three 

 genera (Solenopkorus , Duthiersia, and Ichthyotaenia) have 

 been recorded up to the present from India. They were ob- 

 tained respectively from a python and from Varanus spp. 

 These are in the collection of the Indian Museum. Two other 

 species have been recorded from Ceylon by Von Linstow, but 

 are not represented in our collection. 



V. From Birds. 



{a) From Ceylon, by von Linstow, genera 10, species 13. 

 Of these genera 2, and species 9, were new. Three species of 

 the above (included in three genera), are in the collection of 

 the Indian Museum. 



(6) From India. The preparation of a paper on Cestoda 

 from Indian birds is in progress. Up to the present 16 species 

 have been named, of which four are new. Ten genera are 

 represented. There are still 32 species to name in the collec- 

 tion, which is steadily growing. 



VI. Mammals. The collection comprises 18 species only, 

 distributed in 9 genera, and excluding cystic forms of the genus 

 Taenia. Of the latter we have 5 species only. From Ceylon, 

 Citlotaenia bursar ia has been recorded from a hare, by von Lin* 

 stow, and most of the usual human tapeworms have also been 

 obtained. Doubtless other parasites have been collected by the 

 Veterinary authorities in Ceylon, but of such I have been unable 

 to obtain anv account. 



The rate of growth of some of the larger parasites is very 

 great. On November 29th, 1913, a four-horned antelope died 

 in the Zoological Gardens, Calcutta, and the carcase was sent 

 to the Indian Museum for examination. The animal was born on
