by diagrams taken from preparations now extant, and open to the 

 inspection of any scientific person. Tlie " superior longitudinal 

 commissure " is also new to us. But the most important addition 

 to our knowledge resulting from the labours of Mr. Solly consists 

 in his discovery of some distinct fibres of medullary matter con- 

 necting the cerebellum with the anterior columns of the medulla 

 spinalis : this connection is most satisfactorily proved, and the solu- 

 tion it affords to the understanding of many hitherto anomalous 

 facts in pathology renders this a point of high interest. An ac- 

 curate description of the origin of the motor nerves from, and the 

 termination of the nerves of sensation in, the central organ of the 

 nervous system next follows ; and here again some new features are 

 apparent. The last part of the work is dedicated to the physiology 

 of the brain as elucidated by pathological facts ; but we forbear to 

 enter upon this subject, as it is one of such immense extent. The 

 work is illustrated by twelve beautiful engravings, and the whole is 

 highly creditable to the author. * * *

August 9, A SPECIMEN was exhibited of an Ortyx which 



1836. -^ Mr. Gould regarded as hitherto undescribed. At the 

 request of the Chairman he pointed out the distinguishing peculiari- 

 ties of this new species, which he named and characterized as Ortyx 

 ocellatus. This bird differs from Ortyx Montezuma in several parti • 

 culars, but to that species it is most nearly allied. 



Mr. Gould also brought before the notice of the Meeting two new 

 species of Birds from New South Wales, where they had been col- 

 lected, and subsequently presented to the Society by Captain Sturt. 

 They are referrible to the genus Zoster ops of Messrs. Vigors and 

 Horsfield; a group among the Sylviadce, and of which but two species 

 were known at the time those gentlemen instituted the genus. Mr. 

 Gould placed on the table six additional species, a portion of which 

 was from the Society's collection, and the remainder from his own. 

 In the course of his remarks, Mr. Gould adverted to the surprising 

 augmentation of species which has now taken place in nearly every 

 group in ornithology; and characterized the new species mentioned 

 above as Zosterops alhogularis, Gould, and Zost. tenuirostris, Gould. 

 They are the two largest known species of the genus. 



Notes by W. C. Williamson, Esq., Curator to the Natural History 

 Society, Manchester, on the appearance of rare Birds in the vicinity 

 of Scarborough, were then read, of which the following is an abs- 

 tract. 



*'The prominent position of Scarborough with its projecting 

 headlands separated by deep bays and its high hills covered with 

 wood, render the neighbourhood a favourite retreat for various tribes 

 of birds. Among the spring visitors the Siskin may be enumerated.
