Among other species Mr. Sargent found at Woodville the follow- 

 ing interesting forms : Patula cumberlandiana, Helix exoleia, H. 

 stenotrema, H. spviosa, H. major, Zoidtes Icevigatus, Z. g alar is, Z. 

 intertextus, Z. intermis, etc. 



NOTE ON THE GROUP PANDA. 



BY H. A. PILSBRY. 



During the course of some studies upon certain Australian laud 

 shells, sent by the well-known conchologist Dr. J. C. Cox of Sydney, 

 N. S. W., my attention was drawn to specimens of Bulimus atomatus 

 Gray. Upon examining these shells under a lens, I at once noticed 

 the minute sculpture and peculiar color-pattern characteristic of the 

 two species hitherto included in the section Panda, — H. falconeri 

 Rve. and H. maconelHRve. A consideration and comparison of the 

 shells impresses me with the belief that Panda has heretofore been 

 misunderstood and wrongly grouped. I am disposed to regard it 

 now as a development from the Bulimoid branch of the Helicidce, 

 instead of from the Helicoid stem. The diagnosis of Panda must 

 be enlarged to include elongated forms, {Bui. atomatus and perhaps 

 some other Australian speciesj, but it will not require much change 

 otherwise. The prominent features of the group, as far as the shell 

 goes, are (1) the entirely simple, non-thickened, non-expanded lip, 

 reflexed at the columella, (2) the sculpture of minute, close incised 

 lines, and (3) the painting of fine close wavy brown lines on a 

 yellowish ground. This last character is not invariable, for clear 

 yellow examples of most if not all of the species occur. 



The character of the lip and embryonic whorls separate Panda 

 from Helicophanta and the other sections formerly grouped by me 

 under the generic name Macroon. It will be noted that I formerly 

 included it in that place with doubt, on account of these peculiarities.
