into an hei"mapliroclitt% containing spermalozna and ova. The 

 female unclerfi[oes no such change. He argued that, since in many 

 cases the secondary sexual characters develop independently of 

 tlie ovary or testis, the assumption by the one sex of tlie characters 

 of the other cannot be due to the secretion of a hormone by the 

 gonad, but to some more profound change in the metabolism 

 which may effect both primary and secondary characters. These 

 observations he brought into harmony witli Mendelian results by 

 suggesting that the female Crustacean is homozygous and the 

 male heterozygous to sex; thus the male would be a potential 

 hermaphrodite. From his work on Saccidina he was led to the 

 view that the sessile and parasitic Crustacea, owing to their 

 peculiar mode of life, and the consequent alteration of their 

 metabolism, are hermaphrodite and have all been derived from 

 the male sex, and further that the so-called complementary males 

 of the Cirripedes are in realit}' arrested protandric hermaphrodite 

 individuals. 



In 1907 Geoffrey Smith undertook a journey to Tasmania 

 chiefly with the object of studying the strange fresh-water 

 Crustacean Anasindes, recently discovered there by Mr. G. M. 

 Thompson (Linn. Soc. Trans., ser. 2, Zool., vol. vi. 1894^, p. i:8o). 

 On this expedition, of which he gave a delightful account in a 

 little book entitled 'A Naturalist in Tasmania,' he not only obtained 

 Anasjndes, but also a related but quite new genus Paranasiiides. 

 With the help of this material he was able to bring forward con- 

 vincing evidence of the correctness of Dr. Caiman's contention 

 that the Anaspidoe are the remnant of a group found in the 

 Carboniferous strata and worthy of being placed in a separate 

 division, the Syncarida. He also collected other forms on his 

 travels and published monographs on the land and fresh-water 

 Crayfishes of Australia, in which the geographical distribution, 

 habits, and inter-relntionships of the species are discussed with 

 his usual skill and originality (Proc. Zool. Soc. 1912 and 1913). 

 His papers on '• The Life Cycle of the Cladocera " (Proc. Koyal 

 Soc, 1915), and on "The Genus Lemceodiscus" (Journ. Linn. 

 Soc, Zool., vol. xxxii. 1915, p. 429), may also be mentioned. 

 Several of his works were written in conjunction with others, for 

 he was always most successful in rousing in his friends and pupils 

 the enthusiasm he felt so keenly himself. [E. S. G.] 



The death of Frederic Strattox on the 5th December, 191t!, 

 removes from the Society a Fellow elected 21st January, 1869, 

 and to some of us a close and dear friend. 



He was the son of William Stratton, of Newport, Isle of "Wight, 

 where he was born 16th November, 1840, and in that town he 

 practised as a solicitor for 53 years, and 40 years as Clei^k to the 

 Board of Guardians, retiring in 1903. 



It is as a local botanist that he was best known to this Society. 

 The writer recalls his first meeting with Mr. and Mrs. Stratton 

 at the little inn at the foot of Ben Lawers in August, 1870, and 

 the ascent of that mountain the following day, and that pleasant
