316 On the Spalax of the Grecian Archipelago. 
Size about as in S.m. hellenicus, larger than in anato- 
licus. 
Compared with anatolicus, the skull is of about the same 
general shape, though distinctly larger. Muzzle and nasals 
of similar outlines, but the posterior boundary of the pre- 
maxillary processes and.of the nasals quite unusually com- 
plicated, the interdigitation with the frontals carried to an 
extreme, so that it is impossible exactly to define the limits 
of each bone—hut the middle of the junction is about 
opposite the hinder edge of the anteorbital foramina. This 
complication of the sutures is quite unequaled in other 
members of the genus, and is to a lesser extent repeated 
along the premaxillo-maxillary suture, the close-set inter- 
digitations often nearly equal in length to the palatal fora- 
mina. The course of the two sutures (naso-frontal and 
premaxillo-frontal) not directly transverse as in dolbrugee, 
but bending backwards in the centre, as in e@natolicus, with 
a large naso-basal process on each side. Profile-line from 
lambda to tip of nasals bowed, about as in doldrugee, not so 
straight as in anatolicus. 
Incisors averaging far lighter coloured than in other 
forms, those of the lower jaw always dead white, and in 
the majority of the specimens those of the upper jaw also 
white, one only out of the seven distinctly yellow (though 
still pale yellow) and two more with a faint yellowish tinge. 
In other forms it is rare to find specimens with the upper 
pair not distinctly yellow. No doubt this is an unsatis- 
factory character owing to its variability, and Mehely has 
not used it at all, but the average difference between the 
Lemnos and other forms is so decided as to make it worthy 
of mention. 
Molars with their roots coalesced, about as in anatelicus, 
and therein different from those of hellenicus, of which it is 
said “fan m' und m? alle drei Wurzeln frei; die Alveolen 
dieser Ziihne dreiwabig.”
