THE ZooLocist—JUNE, 18735. 4505 
attention to the following animals:—A Syrian bulbul (Pycnonotus xantho- 
pygos, Hempr et Ehr.), presented by Mr. E. T. Rogers, April 12th; a 
collection of small finches from South America, purchased April 19th, 
amongst which were examples of several species of Spermophila (S. ceru- 
lescens, 8. aurantia, S. lineola and S. hypoleuca) not previously exhibited ; 
and an albino of the common macaque (Macacus cynomolgus) or of the 
Philippine form of the species (M. Philippinensis), brought from Samar, 
Philippines, and presented by Mr. J. Ross, April 23rd. 
Mr. Sclater exhibited and made remarks on a skin of a chick of a casso- 
wary (Casuarius picticollis), received from Dr. George Bennett, of Sydney. 
The bird had been obtained alive from the natives in Milne Bay, New 
Guinea, by Mr. Godfrey Goodman, Staff Surgeon, R.N., when in the 
‘ Basilisk’ in 1873. 
Professor Newton exhibited and made remarks on a series of tracings of 
some hitherto unpublished drawings discovered in the Library of Utrecht, 
representing the dodo and other extinct birds of Mauritius. 
Professor Newton also exhibited and made remarks on two specimens 
of Ross’s arctic gull (Rhodostethia Rossi), one of the rarest of arctic 
birds. 
Mr. H. C. Sorby read a paper on the colouring matter of the shells of 
birds’ eggs as studied by the spectrum method, in which he showed that all 
their different tints are due to a variable mixture of seven well-marked 
colouring matters. Hitherto the greater part of these had not been found 
elsewhere. The principal red colouring matter was connected with the 
hamoglobin of blood, and the two blue colouring matters were probably 
related to bile pigments; but in both cases it was only a chemical and 
physical relationship, and the individual substances were quite distinct, 
and it seemed as though they were special secretions. There appeared to 
be no simple connexion between the production of these various egg- 
pigments and the general organization of the birds, unless it were in the 
case of the Tinamous, in the shells of the eggs of many species of which 
occurs an orange-red substance not met with in any other eggs, unless it 
were in those of some species of cassowary. 
Mr. A. H. Garrod read a note on the hyoid bone of the elephant, as 
observed in two specimens of the Indian elephant which he had lately 
dissected, and showed that the position of the bone in situ had been mis- 
stated by former authorities. 
A second paper by Mr. Garrod containing some remarks on the relation- 
ship of two pigeons (Ianthcenas leucolema and Erythreenas pulcherrima), 
which he lately had an opportunity of examining. 
A communication was read from Mr. G. E. Dobson on the bats belonging 
to the genus Scotophilus, in which he gave the description of a new genus 
and species allied thereto. The specimen in question had been obtained in
