the Common and other Cuckoos , mostly collected by himself and reliable 

 friends , and made remarks on the question of the similarity of the eggs of 

 the Cuckoos to those of the owners of the nest in which they are deposited. 

 — A communication was read from Dr. J. Anderson, F.R.S., containing 

 notes on a small collection of Mammals, Reptiles, and Batrachians made during 

 a recent visit to Algeria and Tunisia. — Mr. F. E. Bed dard, F.Z.S., read a 

 paper upon the Earthworms collected by Dr. Anderson during the same ex- 

 pedition. Amongst them were examples of a new species of the genus Micro- 

 scolex. A second new species of the same genus, based on examples collec- 

 ted by Mr. E. B. Poulton , F.R.S., in Madeira, and proposed to be called 

 M. Poultoni, was also described. — A communication was read from Mr. R. 

 I. Po cock on some Myriopoda and Araehnida collected by Dr. Anderson 

 during the same expedition. — Mr. M. F. Woodward read a paper on the 

 Milk Dentition of Procavia [Hyrax] capensis. The author showed that La- 

 taste's canine has a counterpart in the lower or mandibular series, and he 

 described for the first time two small vestigial upper incisors. He concluded 

 that the teeth named belong collectively to the first or milk set, and that the 

 formulation of the incisors of this genus as -|- is probably due to the occasio- 

 nal persistence of the second upper milk-incisor. — Mr. Oldfield Thomas 

 gave an account of the species of the Hyracoidea, of which Order he had 

 lately examined a large series of specimens. The author recognized fourteen 

 species of this group of Mammals , all of which he proposed to refer to one 

 genus [Procavia.) Besides these, four geographical subspecies were recog- 

 nized. A new species was described as P. Latastei, from Senegal. — P. L.
