The clavicles are only two-thirds as long as broad, and are pierced 

 by a foramen. The scapula is very narrow, with high ridges. The 

 acromion is low and long. 



The humerus is only a fifth longer than broad. 



The pelvis is very narrow, and the bones of the opposite sides are 

 in contact under the acetabulum. The space between the sacral ver- 

 tebrie and pelvis is entirely covered over above by osseous bridges, leav- 

 ing only two pairs of small foramina. 



The femur is three-fourths as long as the tibia. 



The os/rtZci/bn«eislong and slender, slightly tapering and curved at 

 the base. The tip reaches to the base of the terminal phalange of the 

 fifth digit. 



The terminal phalanges are bifid. 



GEOGRAPHICAL DISTRIBUTION. 



The area occupied by the genus ^Sealops, as shown by specimens 

 examined in the preparation of this monograph, has the following bound- 

 aries : The northern boundary passes through central Massachusetts and 

 central Xew York to Lakes Ontario and Erie, thence westward to the 

 southern extremity of Lake Michigan, thence in a northwesterly direc- 

 tion across southern Wisconsin to Elk Eiver, Minnesota, and thence 

 southwestward to the mouth of the Big Sioux River, in South Dakota. 



The western boundary follows in a general way the ninety-seventh 

 parallel and thus includes the eastern fourth of Nebraska, Kansas, 

 and Indian Territory. Continuing in Texas it bends somewhat to the 

 west and follows the ninety-ninth parallel, terminating in Tamaulipas, 

 about 45 miles south of the Rio Grande. 



The southern boundary is the Gulf of Mexico, and in Florida a line 

 connecting Tampa Bay on the west side with Lake Worth on the east. 



An examination of numerous faunal records shows that it is necessary 

 to somewhat extend the range as derived from specimens. In the 

 Northeast, for example, the boundaries should include all Massachu- 

 setts, on the authority of Dr. J. A. Allen ' and Emmons,- and some part 

 at least of Vermont, on the authority of Thompson.^ As regards its 

 absence in northern New York, Baird remarks that Parascalops hreweri 

 is found here "apparently to the exclusion of the more southern species 

 with white naked tail, kS. aiiwdlcus.''''^ I have not met with any record 

 of the occurrence of Scalops in New Hampshire. Mr. G. S. Miller, jr. 

 does not include it among the mammals observed by him in the White 

 Mountain region. If there are records of its occurrence in Maine, they 

 have escaped my attention. While in Hancock County in the summer 

 of 1894, I was informed that the mole was found there, but not abun- 

 dantly. I did not see any evidences of its presence, however, and
