a form which needs comparison with T". sulcifera Sowb. There is a 

 considerable amount of material in the collection, but as Gabb 

 described no new species in this group, we will not enter into the 

 subject further. No revision of any value can be made until 

 Sowerby's types are figured and more fully described. 



In addition to the species named above, Terebra aniitra Dall^^has 

 been described from the Potrero, Rio Amina. 



A very large species of Terebra, distinct from all of the above, is 

 represented by one broken and much worn specimen no. 2972. It 

 has slightly over 4 whorls, with a length of 85.5, diam. 26 mm. 

 There are two raised bands around the posterior part of the whorls.

An abundant species in the Santo Domingo beds. Gabb referred 

 the specimens to T. dislocata. About half of them have spiral lines 

 upon the superior band, as in T. wolfgangi Toula, but there are more 

 spiral cords below the band than in typical wolfgangi. 



Terebra dislocata Say. 



The series referred to this recent species is highly variable, and 

 a further revision may eventually be made. 



There is also a series of small specimens possibly related specific- 

 ally to T. protexta Conr.
