Ecology. "Gastrocopta cristata has, in Kansas, usually been found ... on 

 timbered slopes near streams. In Meade County [Kansas] it was found living in 

 grassy meadowlands of the State Park (Leonard, 1943, p. 239)" (Franzen and 

 Leonard, 1947, p. 345). 



Remarks. Gastrocopta cristata is the most abundantly occurring species in the 

 deposits at the Fordyce Quarry. Forsyth (1958, p. 10) recorded the species from 

 the Yarmouthian of Texas. 



Gastrocopta tappaniana (C. B. Adams) 

 PI. 1, figs. 6a-c. 



Description. Our specimens are in essential agreement with those of Franzen 

 and Leonard (1947, pp. 336, 337) except the present forms have a larger average 

 number of worls (5!/2 compared to an average number of worls of 4-% as given 

 by Franzen and Leonard). 



Measurements. Measurements for Gastrocopta tappaniana are given in Table 8. 



Distribution. Franzen and Leonard (1947, p. 337) reported the distribution 

 of the species as follows: "Ontario; Maine to Virginia; west to South Dakota and 

 Kansas, to Arizona (Pilsbry, 1916, Vol. 24, pt. 93, p. 33). Pleistocene of Nebraska 

 and Kansas .... Gastrocopta tappaniana, essentially a northern species, entered 

 Kansas sometime previous to Upper Pliocene times." 



Ecology. "Its [Gastrocopta tappaniana] most frequent habitat is on shaded 

 slopes near streams. However, it has been taken among grass roots on an unshaded 

 slope near a pasture pond" ( Franzen and Leonard, 1947, p. 337 ) . 



Remarks. This is the first report of Gastrocopta tappaniana from south Texas. 

 The species has been reported from the Yarmouthian of Roberts and Hartley coun- 

 ties in the Panhandle of Texas by Leonard (1950, p. 32).

Hawaiia minuscula ( Binney ) 

 PI. 1, figs. 3a-c 



Description. Specimens are in essential agreement with those described by 

 Pilsbry (1946, p. 421) and Leonard (1950, p. 36). 



Measurements. Measurements for Hawaiia minuscula are given in Table 9. 



Distribution. In North America from Alaska and Maine to Florida and west 

 to the Mountain States; Antilles, Japan, and Hawaii; England and Ireland in hot 

 houses (Pilsbry, 1946, p. 421). Strecker (1935, p. 25) reported this species from 

 the entire state of Texas. 



Ecology. Hawaiia minuscula is tolerant of a wide range of climatic variations. 



Remarks. Leonard (1950, p. 36) reported Hawaiia minuscula from the Lower 

 Pliocene to the Recent, and from the Yarmouthian of Roberts and Hartley counties 

 in the Panhandle of Texas.
