64 REVISION OF AMEBICAN MOLES— TIIVE. vol.xix. 



tliis course, however, tliere does not seem to have beeu sufficient war- 

 rant, and the name slumkl stand as a synonym of .S'. toinisendi. 



All the names thus far considered are to be regarded as synonyms 

 of 8. townsemU, bat in 1855 Dr. W. O. Ayres described the mole which 

 is found in the neighborhood of San Francisco, California, under the 

 name of tSralop.s cnlifornicus. ' This is a snuiller and paler form than tlie 

 tyi)ical Oregon mole, and is recognized as a distinct species, 8. califor- 

 nicH.s, in (ids wtu'k. Whether a type specimen was preserved is uncer- 

 tain, but about 1<S5(I Dr. Ayres sent two si)ecimens to the National 

 Museum from San Francisco,^ which may be regarded as typical. 



Dr. J. A. Allen established a species under the name of JSccqjanus 

 anthonyi, in 1803, fronra specimen obtained in the San Pedro Martir 

 Mountains of Lower California. ' 



The tjpe remains unique, and until more si)ecimens are collected 

 from the same and other neighboring localities the relationships of the 

 species can not be fully determined. 



In 1894 I described, under the name of 8. dilatiis,^ a supposed new 

 species, characterized, like 8. anthonyi, by the i>ossession of one less 

 upper premolar than the usual number, and some other minor features. 

 This species was based on a skeleton from Fort Klamath, Oregon, 

 belonging to Dr. C. H. Merriam. Afterwards, Dr. Merriam sent me 

 two other specimens in alcohol, from the same locality. These had the 

 normal nund)er of premolars. Such being the case, I am disposed to 

 regard the other characters given in the diagnosis as individual rather 

 than specific, and to associate the Fort Klamath mole with *S'. californicus. 



DESCKIPTION OF THE TYPE SPECIMEN OF SCALOPS .KKEUS, CASSIN. 

 No. 3725, TI.S.X.M., Oregoii, U. S. Explor. Exped. 



The type is a skin without a skull. It is in a good state of preserva- 

 tion except for its discoloration from innnersion in impure alcohol. 



From its small size and long claws, it may be judged to be a young 

 individual. It measures as follows: 



lUIll. 



Letigtli of bead and liody 115. 



Length of tail 30. 5 



Length of fore foot (without chiws) 11. 



Length of hmgest foretlaw.... 10.0 



Length of hind foot ( without claw) 21. 5 



Length of longest liiud claw 1.5
