figured two species in Vol. II. of the United States Geological 

 Survey of the Territories. I intended that a reference to Brong- 

 niart's Gatillus should accompany my descriptions in the Report, 

 but I find it was omitted, and therefore insert it in the Proceed- 

 ings. The name Haploscapha I propose to substitute for Gatillus, 

 unless the genus Volviceramus, Stol., should include the species. 

 The singular turn of the beak and very unequal valves in Volvi- 

 ceramus appear to be the only differences between the two groups, 

 and therefore Haploscapha ma}' be retained 011I3' as a subgenus. 

 Nothing nearly related to this genus has ever been found either 

 above or below the chalk. If the cartilage was attached to the 

 grooved margin, it must have been external and very large. It 

 no doubt should be included in the family Amculidse. 



On Mineral Localities in North Carolina. Joseph Willcox 

 said that he desired to place on record some mineral localities 

 which he had visited among the mountains in N. Carolina. 



In Cherokee Co. on the roadside about half-way between Mur- 

 phy and Valleytown, corundum is found well cystallized in kyanite. 

 At the same locality crystals of kyanite, an inch in diameter, occur 

 in quartz. Some of these crystals are almost wholly altered into 

 damourite. 



At Hogback Mountain, in Jackson Co., on land of Thomas 

 Johnston, occur the most beautiful specimens of pink corundum, 

 associated with margarite and tourmaline. 



In Buncombe Co., on the summit of the ridge between the head- 

 waters of Reems Creek and Bull Creek, large garnets are found 

 in mica slate. In Swannanoa Gap, in the same county, a large 

 outcrop of kyanite occurs, extending several miles in a northeast- 

 ern course. At several places on this vein corundum is found in 

 the kyanite, sometimes in crystals more than two inches long. 

 One specimen of kyanite found there has corundum attached to it 

 on one side, while the other side is altered into damourite, which 

 still retains the bladed structure of the kyanite. 



In Madison Co., on the farm of Mr. Carter, near the Burnsville 

 road, 20 miles from Asheville, a white and pink corundum is 

 found, associated with margarite and chlorite. At this place 

 about 1000 pounds of corundum have been dug up ; but it is 

 mixed with spinel so abundantly that it possesses little value for 

 commercial purposes. 



In Haywood Co., a vein of white feldspar (probably albite) has 

 recently been dug out, to a depth of a few feet, in the pursuit of 

 mica. This vein, about 5 feet wide, is walled on each side with 

 gneiss rocks, and contains corundum associated with margarite or 

 damourite. Occasionally corundum is found in a matrix of mica 

 in large plates, resembling muscovite. This corundum is blue, 

 and affords beautiful specimens. He did not observe any indication 

 of serpentine rocks in this vicinit}-.
