observed; all the other elements remain in cartilage and these, apart from 

 the cricoid, fuse more or less together. 



The hyoidean apparatus rests directly upon the top of the larynx 

 and it is only the limbs of the anterior cornua, including the epihyals 

 and stylohyals, that stand out independently ; these project ])osteriorly. 

 Each thyroliyal is broadly paddle-shaped, the blade being in front and 

 directly articulating on either side with basihyal. They only connect 

 with the superior cornu of the thyroid by means of cartilaginous ex- 

 tensions. Parallelogramic in outline, the basihyal is nearly flat, being 

 Ijut very slightly concave from side to side posteriorly, and correspond- 

 ingly convex in the same direction in front. The stylohyals are entirely 

 in cartilage and rudimentary, while both the epihyals and ceratohyals 

 are in bone, each being represented by extremely delicate little rods, 

 making feeble articulations with each other upon either side, and with 

 the basihyal anteriorly. 



It will be of interest to mention, incidently, that Cynucephalus has a 

 very large thick tongue, finely serrated on the thin edge of its semi- 

 circular, anterior margin. The roof of the mouth is peculiarly cor- 

 rugated in curious, transverse, zigzag lines, and these being raised leave 

 strong similar impressions on the sifperior surface of the tongue. This 

 last may be of a post-mortem nature and may not exist during life. 



NOTES ON THE OSTEOLOGICAL MATERIAL REPRESENTING THE GALEOPTE- 

 RID/E IN THEj COLLECTIONS OF THE UNITED STATES NATIONAL 

 MUSEUM. iiuf 



After the typewritten copy of this memoir had been forwarded to me 

 by Mr. McGregor for revision and had received my careful reading, it 

 oecuiTed to me that the value of the memoir would be greatly enhanced 

 if certain parts of it were read by such an eminent writer on mammalogy 

 as Mr. Gerrit S. Miller, jr., curator of the division of mammals in 

 the United States National Musemn. Mr. Miller at the time was in 

 Europe, and did not return to Washington until the early part of Sep- 

 tember, 1910. On the first of the following month 1 took the material 

 I had described, together with the typewritten manuscript to Mr. Miller 

 at the Museum' and after taking up some of the points in the latter, he 

 advised me to make a thorough comparison of the skeletons and skulls 

 of my own collection with those of the far more extensive collection 

 of the Galeopteridse belonging to the United States National Museum, 

 together with a series of skulls of flying lemurs loaned him by the 

 Bureau of Science. Mr. Miller informed me that all the species of these 

 animals belonging to the Malayan fauna were now contained in the 

 genus Galeopterus^ and that the PhLlij)pine species volans was of the 

 genus Cynocephalus. 



There are a number of Malayan species and perhaps subspecies, but
