MiCROTUS AGRESTIS ROZIANUS Bocage. 



1865. Arvicola rozianus Bocage, Mem. Acad. Real das Scieneias de Lishoa, 



N.S., III, pt. 2, p. 7 (articles separately paged). 

 1910. Microtus agrestis rosianus Trouessart, Faune Mamm. d'Europe, 



p. 177. 



Type localitji. — Geria, near Coimbra, Portugal. 



Geographical distrihtition. — Portugal and north-western Spain. 

 Limits of range unknown. 



Diagnosis. — Size and general appearance, so far as is known,* 

 as in Microtus agrestis hailloni ; skull with auditory bullae notice- 

 ably flattened, and so reduced in size that the greatest diameter 

 (from paroccipital process to tip of anterior spine) is contained 

 3 1 times instead of three times in condylobasal length ; teeth 

 relatively somewhat larger than in the other small forms. 



Colour. — Unknown (the only specimens seen have been injured 

 by long immersion in alcohol). 



Skull. — In general foi'm the skull agrees with that of the 

 other small races of Microtus agrestis, but it is immediately 

 recognizable by the small, slightly inflated auditory bulla?, no 

 approach to which has been seen among the considerable number 

 of skulls examined from other parts of Europe. The peculiar- 

 ities of the bulla are best seen in side view. 



* The colour of the only skin examined has heen altered by the action 

 of alcohol.
