IsTOETH AMEEICAIT FAUNA. 



[No. 38. 



(9.6-10); mimdibiilar molar-premolar row, 9.7 (9.5-10). Skull of 

 type (probably a female, though sexed ''male" by collector): Great- 

 est length, 29.3; palatilar length, 11.9; mastoidal breadth, 15.1; mter- 

 orbital breadth, 6.6; maxillary tooth row, 9.2; mandibular molar- 

 premolar row, 9.2. 



Remarks. — The original description of this form was based upon a 

 single specimen which was unique in collections for several years. 

 True,^ on account of insufficient material, placed parvus in question- 

 able synonymy under S. a. australis, where it has since remained. 

 The number of specimens now available from the type region is far 

 from satisfactory, but they show characters sufficient to warrant 

 their separation from australis. The type of S. a. parvus is in worn 

 pelage; True ^ w^as inclined to beUeve on account of the appearance 

 of the skin and the peculiarly worn state of the teeth that the mole 

 had been kept in confinement; there appears no reason for such a 

 conclusion, however, the v/ear in the teeth and pelage of the type 

 being nothing which might not occur in the normal habitat of the 

 mole. Three males from Port Tampa City, Fla., while distinctly dif- 

 ferent from australis, do not appear to be the extreme type of parvus; 

 unfortunately, however, the only specimens from the immediate 

 vicinity of the type locality, except the type, are young. 



Specimens examined. — Total number, 9, as follows: 



Florida: Belleair, 2; Port Richey, 1;^ Seven Oaks, 1; ^ Port Tampa City, 

 Tarpon Springs (type locality), 2.^
