Dr. F. E. Bbddard, M.A., F.R.S., Prosector to the Society, 

 read a paper on " The Anatomy and Systematic Arrangement of 

 the Oestoidea." This paper, the tenth of the series, contained an 

 account of two species of Tapeworms found in a Dongolan Genet, 

 both of which were described as new, one being made the type of 

 a new genus. 



Mr. J. A. Milne read a paper, communicated by the Secretary, 

 on " PaciiiG Salmon : an Attempt to evolve something of their 

 History from an Examination of their Scales," and illustrated his 

 remarks with a large series of lantern-slides. Reasoning from 

 the similarity of their appearance to the scales of the other 

 Salmonidae, he pointed out that all the migi-atoiy species except 

 Onchorhynohus hita remain for at least a year in fresh water 

 before proceeding to the sea — in the Eraser River district, at any 

 rate. He also showed the scale of a Quinnat, and pointed out 

 that it was hardly possible to avoid the conclusion that that fish 

 had already spawned once before it was captured. The ages, and 

 lengths of the diflFerent fishes at varying ages, were also dealt 

 with in the paper. 



A paper, communicated by Prof. J. Stanley Gaediner, M.A., 

 F.R.S., F.Z.S., was received from Miss Kathleen Haddon, con- 

 taining some notes on Peripatoicles woodwardii Bouvier. 



This paper was based on material collected in Western 

 Australia, consisting of twentj^ specimens, male and female, 

 ranging in size from 17 to 46 mm., thus considerably exceeding 

 in length those described by Prof. Bouvier. Various types of 

 coloration are exemplified, some being blue-green with small 

 yellow spots, while others have the yellow pigment increased so as 

 to give a tawny appearance to the animal ; a dark variety of this 

 latter type also occurs. 



Peripatoides ivoodivardii is characterised by the possession of 

 sixteen pairs of legs, and coxal glands are present in the male in 

 all except the 4th, 5th, and 15th pairs. The female has a re- 

 ceptaculum seminis on each oviduct shortly' after its emergence 

 from the ovary. 



Mr. J. C. F. Fryer, M.A., gave a brief account of some field- 

 observations on the enemies of butterflies in Ceylon. During a 

 residence of nearly two years in this island the more common 

 insectivorous birds were watched almost daily. Excluding the 

 depredations of the Wood-Swallow (ArtamicsfascusYieiW.), thirty 

 attacks on buttei'flies were noted, of which thirteen were success- 

 ful. In five of the successes the butterfly was flying badly. Two 

 attacks were made on insects svipposed to be relatively distasteful, 

 a,nd tliree on the mimetic females of Papilio polytes Linn. The 

 Wood-Swallow lived almost entirely on butterflies and confined 

 itself, with few exceptions, to members of the Euplceinse and
