Mr. H. L. Hawkins, ]\I.Se., F.G.S., read a paper, conimnnieated 

 by Dr. Henry Woodward, F.Il.S., Y.P.Z.S., on " The OlassiH- 

 c'ution, INlorphology, and Evolution of the Eehinoidea Holeety- 

 poida,'' illustrated with lantern-slides. The classiiication of the 

 INlesozoic Gnathostoniatous Irregular Echinoids Avas revised, with 

 diagnoses of the families, subfamilies, and genei-a, and a new 

 genus and subgenus wex'e introduced. The anatomy of the test 

 was described for the Holectypoida, and compared with that of 

 (.)ther Orders. The origin of the Irregular Echinoids was dis- 

 cussed, and the Ihies of evolution that they followed were indi- 

 cated and summarized in a genealogical table. 



Mr. H. G. Plimmer, F.R.S., F.Z.S., Pathologist to the Society, 

 read a paper " On the Blood-Paiusites found in the Zoological 

 Gardens during the four years 1908-1911," illustrating his 

 remarks with a large number of lantern-slides. The paper con- 

 tained the results of examination of the blood of 6430 animals, 

 in about 7 per cent, of which pai-asites were found. Many of 

 these parasites were described for the first time, and in other 

 cases the hosts wei-e newly recorded. 



Pi-of. G. O. Sars, C.]\I.Z.S., presented a memoir entitled 

 " Zoological Results of the Third Tanganyika Expedition, con- 

 ducted by Dr. AY. A. Cunnington, 1904-1900. Report on some 

 Larval and Young Stages of Prawns fi'om Lake Tanganyika.'' 



Foin- forms were dealt with in this paper, two of which I'cpi-e- 

 sented very early larval stages, and appai-ently belonged to two 

 quite diti'erent kinds of Prawns, but owing to the difficulty of 

 deciding with any certainty tlie species or even the genei-a to 

 which the}' were referable, they were not named, although a 

 detailed description was given and their probable origin sug- 

 gested. The remaining two forms i-epi-esented a larva in the last 

 stage and a very }'0ung Prawn in the first post-larval stage, and 

 both were referred to a definite species. 



Dr. Robert Broom, D.Sc, C.M.Z.S., communicated a paper 

 '' On the Structure of the Internal Ear, and the Relation of the 

 Basi-cranial Nerves in Bici/nodon, and on the Homology of the 

 jNIammalian Auditory Ossicles,'" tlie first pai't of which contained 

 an account, the first on recoi'd, of the houi/ Jabi/rinth enclosing 

 the internal ear and the nerve foi'amina in I'elation thereto, in the 

 skull of the extinct Reptile, i)?V?//(0(7o//. The author had obtained 

 a cast of the intei-nal ear of a specimen in which the matrix was
