Dagegen möchte ich zum Schhiß darauf hinweisen, daß im Jahre 

 1886 als Balbiani seine Gattung TricJiorhißiclms aufstellte, dieser 

 Name schon vergeben war, da A. Schneider schon 1882 eine Gre- 

 garine, also auch ein Protozoon Trichorhynchus genannt hatte. Nach 

 den Gesetzen der Nomenclatur muß also die Ciliatengattung einen 

 neuen Namen bekommen, als welchen ich den sinnverwandten Namen 

 Mycterothrix^ vorschlagen möchte.

18th January, 1898, — The Secretary read a report on the additions 

 that had been made to the Society's Menagerie during the month of December 

 1897, and called attention to two White-naped Weasels [Poecilogale albiniicJm) 

 from Natal, presented by Mr. W. Champion, F.Z.S.; to a specimen of an 

 apparently new species of Wild Cat from Foochow, China, proposed to be 

 named Felts dominicanorum, presented by Messrs. C. B. Rickett and J. D. de 

 La Touche; to a Lucan's Crested Eagle [Lophotriorchis Lucani) from West 

 Africa, presented by Dr. H. O. Forbes, F.Z.S.; and to a young Bear {Ursus, 

 sp. inc.), from the Andes of Colombia, presented by Mr. William Crosley. 

 — The Secretary exhibited, on behalf of Prof. Robert Collet, F.M.Z.S., a 

 specimen of a supposed hybrid between the Fieldfare [Turdus pilaris] and 

 the Redwing (T. iliacus). — Mr. W. E. de Winton, F.Z.S., exhibited and 

 made remarks on a skin of a Zebra from British East Africa, belonging to 

 a form described by Herr P. Matschie as Equus Burchelli Böhmi, obtained by 

 Capt. S. L. Hinde at Machakos. — Mr. L. W. Byrne read a paper »on the 

 General Anatomy of the fishes of the Order Holocephali'i. The paper contained 

 a brief account of the anatomy of the soft parts of Chimaera monstrosa and 

 Callorhynchus antarcticus^ and a comparison of them with a typical Elasmo- 

 branch such as ScyUium. The alimentary canal was straight and without a con- 

 tinuous mesentery, and the liver very large indeed and fused dorsallyas well as 

 ventrally for some portion of its length, while the spleen and pancreas were 

 closely approximated to one another and compact; the alimentary canal was 

 darkly pigmented in Œimaera, but not so in Callorhynchus. The urogenital or- 

 gans differed somewhat from the normal Selachian type, and a possible corre- 

 spondence between the oviduct of the female and the sperm-sac of the male was 

 considered. The nervous and vascular systems were briefly alluded to. The 

 fins of the Holocephali were also remarked on, especially with regard to their 

 correspondence with those of Scyllitim and the possibility of the peculiar tail 

 of Chimaera being really of a heterocercal nature, modified perhaps by the 

 exigencies of a deep-water habitat. — Dr. W. G. Ridewood read a paper 

 »on the Development of the Hyobranchial Skeleton of Alyles«, in which he 

 showed that of the two axial cartilages present in the larval hyobranchial 

 skeleton of this Batrachian the anterior one disappears completely, while the 

 posterior, which is remarkable in extending back to the laryngeal sinus, 

 persists as the central part of the hyoid. He also demonstrated that the
