Natural History Notes from North Caroliiia.

43. Z. iniernus Say. Found in rotting logs, and under 

 them; has the habit of Patula perspectiva, with which it is 

 nearly always associated. This species is out of place as 

 usually arranged by the systematists, who have placed it with 

 Zonites under Gastrodonta. The shell is not that of Zonites 

 or any section of the genus. It is of the patuloid type, and, 

 in fact, is, as well as the animal, a transition form. Nothing, 

 it seems to me, could be more suggestive to the thoroughly 

 earnest student of our shells than this species. Its habits, its 

 shell and its anatomy will well repay the systematist for any 

 time expended on them. 



44. Z. multidentatus Binn. Typical specimens occur in the 

 leaves, with the other species having the same habit, but 

 somewhat sparingly. 



44. Philomycus carolinensis Bosc. This slug is abundant in 

 fields about stumps and old logs, and frequently ascends trees 

 to a height of fifty or sixty feet, especially in wet weather. 

 The markings run to an excess of variation that would set the 

 variety mongers crazy. The general ground color also varies 

 from very dark gray in some specimens to very light gray or 

 cream color in others. 



45. P. Wetherbyi W. G. B. This very distinct form has 

 nearly the same habit as the above, but lives in leaves in damp 

 places during Winter and hot dry weather in Summer. During 

 rainy seasons it ascends trees to a great height, being some- 

 times found on the upper branches. 



46. P. hempkilli W. G. B. This species also occurs here, 

 but not so abundantly as the others. It is a darker colored 

 and less marked species than its associates. It is also more 

 slender. It is a very distinct form, and the wonder is how it 

 so long escaped notice. 



47. Patula alternata Say. This species is represented here 

 only by the var. fergusoni Bid, very beautiful shells, and in 

 every way typical. The type form and the variety mordax 

 are not found here. The snail in question has the tree- 

 climbing habit, and it may often be found in the moss on trees 

 from ten to fifty feet from the ground. 



48. P. perspectiva Say. Occurs in rotting logs, at the roots 

 of dead trees, and always about decaying timber. The form 

 is typical and exhibits little variation. I have collected, in
