continuous, leading to the condition seen iu the Anabaciacere and Lopho- 

 serinse. The microscopic value of the septa and synapticula is considered, 

 and these last structures are shown to be produced in some instances before 

 the thin septum, which very well unites to the larger one; while the 

 synapticular structures are not always continuous with those of the larger 

 septa. The direction of the ultimate histological elements of the two 

 structures differs, and there is connective tissue between them.

 the chair. 



Messrs. F. W. Burbridge and Joseph Johnson were balloted for and

Dr. W. C. Ondaatje called attention to a Eed Coral from Ceylon. 



A paper was read by F. Maule Campbell " On the pairing of a Spider, 

 Tegenarla guyonii, and description of certain sexual organs in the male." 

 Some of the habits of spiders, and especially of this species, were mentioned 

 as bearing on the conflicts of the sexes which were described, and the 

 specific benefits which would arise from them referred to. The paper con- 

 cluded by a note on certain glands (probably of spinning function) situated 

 on the convexity of the abdominal sexual region. The ducts, considerably 

 convoluted, open through transparent tubular spines, arranged trausversely 

 to the axis of the body of the spider. Two papilla-like processes below 

 the opening of the genital sinus were described. — J. Murie

The Secretary made a report on the additions that had been made to 

 the Society's Menagerie during the month of January, and called attention

A letter was read from Mr. F. C. Selous, dated from the Matabele 

 Country, on the possibility of obtaining a White Rhinoceros. 



Extracts were read from a letter received from the Rev. G. H. R. Fisk, 

 of Cape Town, giving an account of the habits of some Reptiles which he 

 had had in captivity. 



A communication was read from Messrs. Salvin and Godman, con-

 from Ferguson Island, one of the D'Entrecasteaux group, which they 

 proposed to call 0. insularis. 



Mr. Sclater read some further notes on Tragelaphus gratus, and exhibited 

 drawings of both sexes of this Antelope, taken from specimens living in the 

 Menagerie of the Jardin des Plantes, Paris.
