between the last two dorsal vertebrae, and tlie most posterior between 

 the last lumbar and first sacral. 



The sternum comprises G segments including the manubrium. The 

 latter is as long as the remaining segments combined, and has the 

 facets for the first pair of ribs at the beginning of its posterior third. 

 The keel is broad, especially anteriorly. The upper surface is broad 

 in front of the ribs, and furnished with a median crest. 



The humerus is about one-third longer than broad, while the clavicle 

 is e(pially as long as broad. 



The bones of the pelvis are approximated under the acetabula, but 

 those of the two sides do not meet. The pubic bones are widely diver- 

 gent ])osteriorly. The iliac bones are completely fused with the sacral 

 vertebrae above, leaving- only two small foramina on each side. The 

 last sacrnl vertebra has a short broad transverse process (as in Condy- 

 lura), M-hich does not touch the pelvis. 



In the manus the osfalciforme is short and very broad at the base. 

 Its distal end rests against the proximal end of the first metacarpal. 

 The terminal phalanges are irregularly bifid. 



Tibia one-sixth longer than the femur; the fibula uniting with it 

 slightly above its middle point. 



GEOGRAPHICAL DISTRIBUTION. 



On the basis of the specimens and records examined, the range of 

 the species may be stated to extend from the mountains of IS^orth Caro- 

 lina and "West Virginia and southeastern Ohio in a northeasterly direc- 

 tion across Pennsylvania, New Jersey, Xew York, and the Xew England 

 States to New Brunswick. The northwestern boundary skirts Lake 

 Erie and Lake Ontario and follows thence the St. Lawrence Eiver to 

 Quebec and perhaps to the ocean; but for want of definite records as 

 regards New Brunswick, it must be deflected southward to follow the 

 eastern boundary of Maine, with a slight inclination outward at Passa- 

 maquoddy Bay to include Charlotte County, New Brunswick. 



The specimens examined are, with two exceptions, all from localities 

 within the following boundaries: Beginning at Cleveland, Ohio, the 

 line skirts the southern shore of Lake Erie and of Lake Ontario to a 

 point near the exit of the St. Lawrence Kiver; thence it passes across 

 New York to Lake George; thence across extreme western Massachu- 

 setts to northwestern Connecticut; thence in a southwesterly direction 

 across Pennsylvania to the vicinity of Pittsburg; and thence to the 

 starting i)oint, Cleveland, Ohio. The two outlying- points from which 

 specimens have been examined are Quebec, Canada, and Magnetic City, 

 North Carolina, at the foot of Eoan Mountain. 



From the ncords the range, as indicated above from specimens, 

 receives large extensions, chiefly toward the northeast. The North 

 Carolina locality is connected with the main area through the record of 

 Audubon and Bachmau. They report having seen one near Bed Sulphur
