542 Dr. C. W. Andrews — Fossil Mammals from Salonica. 



in the several structural points referred to above, but by its much, 

 earlier date, H. hrevirostrts occurring in Upper Pliocene beds in 

 France, associated with Equus stenonis. Syce^ia rohista, Weithofer,' 

 from the Val d'Arno, is regarded as identical with H. hrevirostrts. 

 Erom IT. gigantea our fossil is sharply distinguished by the characters 

 of the upper carnassial. There seems no doubt that the present is 

 a new species, for which I propose the name Mycena salonicce, n.sp., 

 the type-specimen being the right maxilla (B.M., JN'o. M. 11413) 

 above described and figured : it was collected by the Rev. Wilberforee 

 Cooper, C.F., and reached the Museum through the agency of Cvril 

 Brett, Esq., in 1916. 



The remains of Uipparion, as ah-eady noted, are from the village of 

 Dudular, N.N.W. Salonica : they were collected by Capt. Seymour 

 AV. Davies, Il.A.M.C, and presented by him to the Museum. The 

 specimens (M. 11585-6) include the occipital portion of a skull, 

 both maxillae, premaxillae, symphysial portion of mandible, and 

 some fragments of limb-bones. 



The portions of the skull seem to have belonged to a rather large 

 individual, which, judging from the presence of a well- developed 

 canine, was probably a stallion. The teeth are in a most perfect 

 state of preservation, at least on the right side, where the outer coat 

 of cement, so often lost, is completely preserved. There seems to be 

 no doubt that these remains are referable to the widely-spread 

 species Hipparion gracile. 



The length of the molar-premolar series is 149 mm., and the width 

 across the occipital condyles is 78 mm. The limb -bones are 

 represented by portions of tibiae and of a radius and ulna. 



All the above specimens terminate in sharp, clean fractures, 

 indicating that much was left behind, and that careful collecting 

 might yield very important results. 



Portions of a mandible and limb-bones of a large Mastodon from 

 the island of Imbros, off the mouth of the Dardanelles, were 

 collected by Lieut. Riffault, E.A.M.C., and Col. Girvin, A.M.S., 

 and were sent to the Museum by Capt. Percival T. Priestlv, 

 M.B., E.A.M.C, in 1916 (M. 11587-8). 



The remains found in this case are unfortunately very imperfect, 

 and were enclosed in a very refractory matrix. The chief specimen 

 is the imperfect right ramus of a mandible with one broken molar 

 in situ. This tooth seems to have been trilophodont : the outer 

 lobes are worn into a trefoil pattern, the ends of the trefoils being 

 formed by cusps blocking the transverse valleys, as in such forms as 

 Tetrahelodon angustidens. The bone is broken away immediately 

 behind the tooth, but extends in front of it as far as the posterior 

 part of the symphysis, the length of which cannot be determined. 

 The ramus is deepest at the back, narrowing gradually towards the 

 symphysis. The sharp alveolar border is nearly straight, while the 

 ventral border curves down slightly at the symphysis. There is 

 some evidence that there was a lower incisor of considerable size, and 

 in that case the species would be referable to the genus Tetrahelodon.
