The following, to No. 4630 inclusive, are parts of the same skeleton of the Philippine 

 Colugo, or Flying Lemur (Galeopitheeus philippinensis): 



Presented by Hugh Cuming, Esq., F.L.S. 



4618. The right scapula. 



It is remarkable for the long and straight coracoid : the acromion is flattened and ex- 

 panded : the lower costa is bent out to form a ridge, like a second spine. 



4619. The right humerus. 



It is long and slender, with a much-produced deltoid ridge commencing between the outer 

 and inner tuberosities, which are subequal and low : the inner condyle and the intercondyloid 

 space are both perforated : the canal for the medullary artery penetrates the back part of the 

 upper third of the shaft and descends obliquely. 



4620. The right radius. 



It is longer and more slender than the humerus. 



4621. The right ulna. 



It is still more remarkable for its slenderness, and gradually tapers to a point at the distal 

 end, which does not articulate with the carpus. 



4622. The ossa innominata. 



The ilium retains the long and slender form characteristic of its essential nature as a pleur- 

 apophysis : the divergence of the pubes and ischium, which are also long, occasions an 

 unusually wide ' foramen obturatorium.' 



4623. The right femur. 4624. The right tibia.
