or 24th day, and lasted for three days; the discharge was profuse, and first 

 appeared in about the 9th or 10th year. All the Chimpanzees, with the cha- 

 racters of "Johanna", appeared to come from the West Coast of Africa, south 

 of the Equator. "Johanna" had the habits and mental temperament of the 

 Chimpanzee; her teeth, hands, nose, and ears were also characteristic of that 

 species. Evidence was produced to show that the Gorilla, in many of its 

 characters, was the most primitive of the three great Anthropoid Apes, and 

 probably retained more of the features of the common anthropoid parent 

 than either the Chimpanzee or Orang-utan. The Chimpanzee was to be 

 looked on as a Gorilline derivative in which the teeth had undergone very 

 marked retrograde changes , accompanied by corresponding changes in the 

 skull and muscles. The various races or species of Chimpanzee described 

 differed in the degree to which they had lost their Gorilline characters. Most 

 of the characters which had been ascribed to these species were really only 

 characters of individuals, or were due to age or sex. The skulls of the Cen- 

 tral-African Chimpanzee certainly showed distinctive features. It was prob- 

 ably a well-marked race. There was not enough material collected as yet to 

 allow a definite statement to be made as to the distinctive features of other 

 races. Du Chaillu was the best guide up to the present time, and the Cen- 

 tral African form might be added to the three species described by him. It 

 was possible, however, that it might be found of the Chimpanzés, what Se- 

 lenka has shown to be true of the Orang-utans, that these species were of 

 the nature of local forms. — Mr. W. L. H. Duckworth read a note on the 

 specific differences in the Anthropoid Apes, dealing in the first place with 

 a specimen in the Zoological Museum at Jena. The specimen in question 

 was labelled "young female Gorilla", but Mr. Duckworth had come to the 

 conclusion that it was not a young animal, and that it was a Chimpanzee 

 and not a Gorilla. In the second place, the work of Professors Kükenthal 

 and Ziehen on the 'Cerebral Hemispheres of the Primates' was dealt with, 

 and the failure of these authors to recognize the identity of Gorilla engena 

 and Troglodytes Savagii was commented on. Lastly, the reported occurrence 

 of a Gorilla at Stanley Falls on the Congo was mentioned, though the spe- 

 cimen in question seemed to be rather a Chimpanzee than a Gorilla. — Prof. 

 B. C. A. Windle and Mr. F. G. Parsons, F.Z.S. presented a paper on the 

 "Muscles of the Head, and Forelimb of the Edentata". The results were 

 obtained by comparing the already existing scattered literature with a series 

 of recent dissections. In some cases five or six records of the same animal 

 were present, and thus the risk of stating individual variations as the nor- 

 mal arrangement was lessened. This paper was a purely technical record, all 

 generalizations and deductions being reserved for a second part. — Mr. Martin 

 Jacoby, F.E.S., contributed a second part of a paper entitled "Additions 

 to the Knowledge of the Phytophagous Coleoptera of Africa". It contained 

 descriptions of 72 new species of the groups Halticinae and Galerucinae, 6 

 of which had been made the types of new genera, — P. L. S dater. Secre-
