The shell varies a good deal in size and shape. Some speci- 

 mens are almost exactly cylindric, while others are distinctly 

 swollen above. There is a tendency for the whorls to over- 

 hang the suture in some specimens. The internal lamellae 

 vary somewhat in position, but the palatal thread always lies 

 within the front or ventral part of the penultimate volution. 



The locality, Dallas, given by Strebel on the authority of 

 Boll, is far to the north of the other localities, which lie in 

 adjacent counties south of the middle of the State. If correct 

 this is the most northern locality for Holospira. Menke's 

 types may have come from New Braunfels, an old German 

 colony. They were collected in Texas by G. A. Goldfuss, in 

 whose honor the species was named. The figures are from 

 New Braunfels specimens.
