bones, casts, and photographs of the large extinct struthious bird from the 

 Diproiodon-heàs at Lake Callabonna, South Australia, which had been re- 

 cently discovered and named by him Genyornis Newtoni^ and gave a history 

 of the principal facts connected with its discovery. — Mr, G. E. H. Barrett- 

 Hamilton, F.Z.S., exhibited a pair of Walrus-tusks from the Pacific, be- 

 longing to the species which has been named Trichechus ohesus^ and gave 

 some account of the Cetaceans and Seals of the North Pacific. — Mr, A. 

 Smith Woodward, F.Z.S., read a description oi Echidnocephalus Troscheli, 

 an extinct fish from the Upper Cretaceous of Westphalia, proving its identity 

 in all essential respects with the existing deep-sea genus Halosaurus. Spe- 

 cimens in the British Museum exhibited most of the essential characters of 

 the skull and opercular apparatus, also the enlarged scales of the ventrally- 

 situated slime-canal on the trunk, of Halosaurus. — Mr, G. A. B oui enger, 

 F.R,S,, read a note on Acanthocybium Solandri, which recorded the occur- 

 rence of this fish in the Arabian Sea. A specimen of it, transmitted by Sur- 

 geon Lt.-Col. Jayakar, C.M.Z.S,. from Muscat, had recently been received 

 by the British Museum, in which the species had been previously represented 

 only by a dried head from the Atlantic. — Mr. W. E. de Winton, F.Z.S., 

 made some remarks on the distribution of the Girafi'e, and gave the syno- 

 nyms and more definite descriptions of the two existing forms. Giraffa ca- 

 melopai-dalisj Linn., was fixed for the name of the Three-horned northern 

 form, and G. capensis, Less., for that of the Two-horned southern species. 

 — A communication was read from Dr. Alfred Dug è s containing a descrip- 

 tion of a new Ophidian from Mexico, which was proposed to be named Oreo- 

 phis Boulengeri, gen. et sp. nov. — A communication was read from Mr. C. 

 Davies S h erb or n, F.Z.S., containing a list of the exact dates of the publi- 

 cation of the parts of the Natural History portion of Savigny's 'Descrip- 

 tion de l'Egypte'. — Mr. F. E. Beddard, F.R.S., read a paper on the ana- 

 tomy of the Tropic-bird [Phaéton] of the order Steganopodes, amongst which 

 he considered it to occupy a low position near Fregata. — P. L. Sclater, 

 Secretary.

January 11, 1897. — Dr. G. S. Huntington read a paper entitled 'A 

 Contribution to the Myology of Lemur brunneus '. The paper deals with some 

 of the ventral trunk muscles and the appendicular muscles of the forelimb 

 and pectoral girdle. A comparison of the structure of these muscles with 

 the corresponding parts in other members of the suborder shows L. brunneus 

 to possess marked primate characters in the arrangement of the pectoral 

 girdle muscles and the muscles of the proximal segment of the anterior limb. 

 This is especially evident in the lateral recession of the pectorales ; the com- 

 pound character of the ectopectoral insertion, the junctions of a pectoralis 

 abdominalis with the typical entopectoral insertion , and the presence of an 

 axillary muscular arch, derived from the tendons of the latissimus dorsi and 

 connected with the deep plane of insertion of the ectopectoral tendon. The 

 presence of a third or inferior portion of the coraco-brachialis is noted in 

 addition to the upper and middle portion usually present in the Lemuroidia. 

 The ventral trunk muscles present a distinct carnivore type in their arrange- 

 ment, instanced by the high thoracic extension of the rectus abdominalis, the
