developed stride, subangular periphery, &c. Pfeiffer was un- 

 acquainted with the habitat. Sowerby and Reeve both assign 

 it to St Domingo 'under the name of Cumingii, Mr. V. P. 

 Parkhurst found one dead specimen near Port au Prince, Haiti. 

 At or near Port au Prince, Mr. Parkhurst also found Cydotiis 

 floccosus, Shuttl., Cyclostomits A'ninensis, Pfr., Chondropoma 

 serraticostata, Wein., Helicina rugosa, Pfr. and Faivana, Pfr., 

 Helix piibescens .? Pfeiffer, crispata and mdistincta, Fer., cepa 

 Miill., Cylindrella gracilicollis, '?6r., Macroceramus Klatteanus, 

 Bid., and some species not yet determined and beheved to be 

 new. 



Helix (Microphysa) Ingersollii, n. s. Discovered by Mr. E. 

 Ingersoll in various localities on the S. W. of Colorado. At 

 Howardsville, Baker's Park, it was abundant in wet places on 

 the mountains 9,300 ft. above the sea. The finest specimens 

 were found at Cunningham Gulch, clinging to the almost ver- 

 tical face of a trachyte cliff, at an elevation of 11,000 feet, 

 found also on the Southern Slopes of the Saguache Mts., on 

 the Las Animas and Laplata Valleys, it inhabits similar sta- 

 tions to the Succinea. According to Mr. Binney the jaw is of 

 the same type as H. Lansingii. It can scarcely be compared 

 with any known N. A. species. 



Geostilbia Giindlachi, Pfr. Dr. van Rygersma who has had an 

 opportunity of examining the animal, describes it — "as having 

 four tentacles, the 2 lower ones very small and scarcely 

 perceptible, the upper thick, cone elongated, without any black 

 spot, indicating eyes. The animal is of a citron color, the 

 foot long and narrow. 



The species was described as Achatina Guiidlachi by Pfr. 

 in 1850. Von Martens places it in Aciada (subgenus of 

 Cionella), Arango in Ca'dlianella, Bourg. and M. Crosse 

 in Geostilbia. The dentition is of the same type as Ccedlian- 

 ella adcula and Stenogyra hasta, Pfr. . The ribs of the jaw are 

 similar to those of H. Lansingii. It is a widely distributed 

 species, occurring in Cuba, Jamaica, Haiti, St. Thomas, St. 

 Martin and Barbadoes. A closely allied if not identical species 

 has recently been found in Guadeloupe by M. Marie.
