Sir George F. Hampson, Bt., F.Z.S., presented a paper giving 

 a list of the Moths collected by Mr. Sheffield A. Neave, F.Z.S., in 

 Rhodesia north of the Zambesi and the adjacent Katanga District 

 of the Congo Free State, nearly two hundred new species being 

 described. 



The Moth fauna of the district is mainly of a West African 

 type, with a considerable admixture of East African and Mashona- 

 land forms. As there are no high ranges of mountains or deep 

 river valleys the fauna presents a very uniform tropical African 

 character, with no high mountain forms or forms peculiar to the 

 faunas of the drier parts of Southern or Northern Africa. 



The Secretary read a paper on "The Urogenital Organs of 

 Chimcera monstrosa" by T. H. Burlend, M.A., B.Sc, communi- 

 cated by Prof. W. N. Parker, Ph.D., F.Z.S. 



This paper dealt with the urogenital organs of Chi?nce7'a, both 

 immature and adult of each sex. Much of the early work of 

 Leydig and Hyrtl, which later writers had ignored or disputed, 

 was now confirmed and supplemented. The kidney of the young 

 male became differentiated at maturity into an anterior portion, 

 the " Leydig's gland," with a function like that of the prostate 

 gland of higher vertebrates, and a posterior portion, which retained 

 its urinary function. Concomitant changes occurred in the 

 structure of the sperm-duct. Vasa efferentia were present in the 

 male, and these passed directly into a collector with which the 

 sperm- duct was continuous ; hence an epididymus, as usually 

 defined, was absent. The adult female was shown to lose the 

 distinct urogenital sinus found in the young animal ; further, the 

 term " digitiform gland " was suggested as more suitable for the 

 structure usually called the " receptaculum seminis." 



The next Meeting of the Society for Scientific Business will 

 be held on Tuesday, the 15th March, 1910, at half-past Eight 

 o'clock p.m., when the following communications will be 

 made : —
