Mr. MACLEOD Yearsley, F.R.O.S., exhibited an aneurysm of 

 the abdominal aoi-ta from a Jaguar and photographs of one in a 

 Turtle. Both specimens were in the College of Surgeons' Museum, 

 the latter being Hunterian. The aorta in the case of the Jaguar 

 was extensively atheromatous. 



A communication fi-om Mr. Guy A. K. Marshall, F.Z.S., 



entitled "A Monograph of the Coleoptera of the Gexm^ Hippo- 

 rhinus Schh.," was read. It contained an envimeration of the 

 138 known species of the genus, of which 50 were described as 

 new. 



A paper on " Proposed Additions to the accepted Systematic 

 Characters of certain Mammals " was read by Dr. Walter Kidd, 

 F.Z.S., in which two groups of phenomena were considered. 

 First, the arrangement of hair on the naso-frontal region was 

 dealt with and two leading types described ; second, the distri- 

 bution of whorls in certain forms was held to be of sufficient 

 importance to be included in the description of the species and 

 genera. In both divisions of the subject the results were shown 

 to agree with accepted classification. 



Dr. W. G. RiDEWOOD, F.Z.S., read a shoi-t paper on " Some 

 Observations on the Skull of the Girafie," based upon the exami- 

 nation of a series of sections taken at right angles to the median 

 plane of the head, and more or less transverse to the axis of the 

 skull. The investigation was primarily undertaken with the object 

 of arriving at an explanation of the fact that the bases of the paired 

 horns or ossicusps of the adult are much more hollowed out than 

 are those of the young animal ; but other features of interest 

 concerning the extent and relations of the cranial sinuses were also 

 dealt with. 



Mr. F. E. Bedbard, F.R.S., read a note on the brains of the 

 Potto {Pe7'odicticus potto) and the Slow Loris [JV^ycticebus tardi- 

 gradus), and made some observations upon the arteries of the 

 brain in certain Primates that had died in the Society's Menagerie. 



Dr. C. W. Andrews, F.Z.S., gave a description of the bones of 

 the pelvis and hind-limb of Mullerornis betsilei, one of the small 

 forms of birds of the family ^pyornithidfe. Except foi' their 

 smaller size and I'elatively more slender proportions, no important 

 differences from the corresponding bones of such species as 

 JEpyornis mulleri or hildehrandti were observed, and no light was
