The iutervertebral ossicles are well developed. The sternum consists 

 of five segments, inclndiug the manubrium, whicli is as long as the 

 other segments combined. It has a deep keel and short lateral proc- 

 esses near the anterior end for the articulation of the first pair of ribs. 



The scapula is very narrow, with the iufra-spinous fossa obsolete, 

 the acromion prominent and n)oderately uncinate. 



The humerus is one and one-half times as long as broad, and the 

 clavicle nearly twice as long as broad, hence much less compressed 

 than in Scalops. 



The pelvis is contracted, but the iliac bones do not quite meet below 

 the acetabula. There is no pubic symphysis. The sacrals dip down- 

 ward behind the line of the acetabula and there is no osseous connec- 

 tion between them and the ischium. 



The tibia is as long as the foot (including the claws) and one and 

 two-thirds times as long as the femur. The fibula united with it above 

 its middle i)oiut. 



The terminal phalanges of the manus are bifurcated. The os falci- 

 forme is prominent and its distal extremity rests against a sesamoid 

 at the outer base of the first metacarj)al. 



GEOGRAPHICAL DISTRIBUTION. 



The range of the star-nosed mole covers an area extending on the 

 Atlantic Coast from Xew Jersey to the mouth of the St. Lawrence 

 River, and tlience westward (with the northern limit at 51° !N^. hit.) to 

 James Bay, JNIanitoba and Minnesota, and southward (in the mountains) 

 to the boundary of South Carolina. The existence of the species in 

 the Indian Territory and on the Pacific Coast is doubtful. 



The latest monographer of the insectivora. Dr. G. E. Dobson, gives 

 the range of the species as follows: 



North America, widely distributed, from Nova Scotia and Hudson Bay to South 

 Carolina and northern Tenne.ssee, extending westward through the States to Oregon 

 and Washington Territoi'y.' 



I am unable as indicated above to trace the species through so wide 

 an area, either from the specimens examined or from the records in lit- 

 erature. The specimens examined in the preparation of this work were 

 from an area covering practically the whole of the iNew P^ngland and 

 Middle States, with outlying localities in the Hudson Bay region, Nova 

 Scotia, Quebec, the mountains of North Carolina, and finally Minnesota. 

 The boundaries of the area referred to are somewhat as follows: On 

 the souths beginning at Washington City, and INIarshall Hall, Mary- 

 land, the line extends to Cleveland, Ohio; from thence along the Lakes 

 to Ottawa, Canada; thence through Montreal to Eastport, Maine. The 

 southeastern boundary extends from Washington to New York, thus 

 excluding southern and eastern Maryland, Delaware, southern New 

 Jersey, Long Island, and southern Connecticut. The outlying points
