 of the acute ribs. 



T. ccelata Reeve is a broader shell, which likewise possesses a 

 similar sutural taenia. Though small, the type appears adult. 



EDITORIAL NOTES. 



We regret to have to record the death of R. J. Lechmere Cuppy, formerly a 

 member of this Society, and well-known for his work in connection with the 

 mollusca, both living and fossil, of the Island of Trinidad. He was born in London 

 on August 15th, 1836, his father being the Hon. R. Guppy, barrister-at-law. By 

 profession a civil engineer, he subsequently entered the Colonial Secretary's office 

 in Trinidad, and in 1868 became Chief Inspector of Schools, a post which he held 

 until 1891. Guppy contributed papers on recent mollusca to the 1st, 2nd and 7th 

 volumes of this Journal, and many others to the Annals and Mag. Nat. Hist. 

 and other periodicals. He was a prolific writer on the geology of Trinidad and 

 other West Indian islands, and contributed largely to the publications of the 

 London Geological Society. He died in Trinidad on August 5th, 1916, a few days 

 before reaching his 80th birthday. I am indebted to Mr. R. B. Newton, an old 

 friend of Guppy's, for these notes. 



Professor Boycott sends the two following notes : — In ihe Journal of Physiology 

 (vol. 50, 1916, p. 370) I. Leitch records a number of interesting observations on the 

 function of the red respiratory pigment haemoglobin in Planorbis and Chirono7iius. 

 He concludes that the animals are thereby able to make use of the oxygen in a 

 deficiently aerated medium and that there is not enough haemoglobin to be of any 

 practical use as a store of oxygen. 



In \}c\& Journal of the Royal Army Medical Corps (yq\. xxvii., 1916, p. 171) there 

 is an interesting illustrated account, by R. T. Leiper, of some Egyptian freshwater 

 mollusca with special reference to the occurrence of larval forms of parasitic trema- 

 tode worms. The intermediate host of Bilharzia mansoni is Planorbis boissyi, 

 while the larvae of the other species parasitic in man, Bilharzia haetnatobitcm, have 

 been found in Bulliniis contortns, B. dybowski ( alexandrina ) and B. innesi. It 

 appears that if these snails could be killed off, substantial progress might be made 

 in dealing with Bilharzia disease, which is one of the curses of Egypt. 



We welcome the appearance of part 22 of Mr. Taylor's Monograph, comprising 

 the British species of Hygroi/u'a, with the exception of granulata Alder, and 

 Helicodonta obvohita Mull. Mr. Taylor is to be warmly congratulated on maintain- 

 ing the high standard of his work in spite of the difficulties caused by depletion of 

 staff, and the illustrations are as numerous as ever. The present number has a 

 particularly interesting series of portraits. Apparently Lowe's record of H. revelata 

 in a Notts, wood still needs elucidation. It is an extremely improbable one, and 

 anyone who wi uld ascertain what has become of Lowe's collection and, if possible, 

 examine the supposed revelata, would do a real service.
