34 FOSSILS FBOM SOUTHERN UNITED STATES— DALL. vol xviii. 



gonata, new species. Rastula, both fossil and recent, lias few American 

 species. T. evansi, Gabb, in the older Miocene of Chiriqui, Central 

 America, seems to be an analogue of T. sim2)le.v, Conrad, of the Chesa- 

 peake Miocene of Maryland. The latter is abundant in the beds of 

 St. Mary's River, where it is accomi)anied by a variety altior^ Dall, and 

 by a small, smooth species common to the older beds at Shiloh. New 

 Jersey, for which the name inornata is proposed. 



In early publications on our Tertiary, species were sometimes de- 

 scribed as Terebra which should now be referred to other families. 

 Such are T. costata, I. Lea, 1833 (not of Borson, 1823, -f leai, de Gre- 

 gorio),T. (jracilis and T. multiplicata., I. Lea; and also T. dainda awd 

 coustricta, H. C. Lea, which belong to the Cerithiacea. There are also 

 a number of catalogue names or synonyms, such as T. perlata, Con- 

 rad (= vemista, Lea); T. petit ii, Kiener (— coarse var. of T. (lidocata)', 

 T. loxonema, Conrad (i)robably intended for one of the varieties of 

 T. simplex, hnt never described or figured); T. sublirata, Conrad (a 

 catalogue name here revived), and T. tuberculosa, Nelson (unfigured, 

 1870) which is not the tuberculosa of Hinds (1813). 



TEREBRA (HASTULA) HOUSTONIA, Harris, new species. 



This species differs from T. venusta by its less rectilinear sides, its 

 more inflated whorls, and drawn-out si)ire of somewhat i)ui)iform ap- 

 pearance, its straight and simple pillar, its more arched longitudinal 

 riblets, which are usually obsolete on the last whorl, and by its feebler 

 spiral striation. Longitude, 29; maximum diameter, 5 mm., in a speci- 

 men having ten whorls beside the smooth, small, pointed nucleus of 

 three and one-half whorls. 



Tyx)es.—l^o. 0031, U. S. N. M. ; Claiborne, Alabama. 



The species will be fully described and illustrated by Mr. (t. I). Harris 

 in his report on the Texas Tertiary fauna. It is found in the lower 

 bed (Lisbon horizon) at Claiborne Bluff, and also in the Texas Eocene. 



TEREBRA GABBI, Dall. 



Terebra rohusta, Gabb, Geol. Sauto Domingo, p. 224, 1873; not of Hinds, Proc. 

 Zool. Soc, LoncL, p. 149, 1843. 

 Shell large, strong, with a slender, strongly sculptured spire, and 

 later smoother, rapidly enlarging whorls, with a nearly peripheral, nar- 

 row, spiral <'olor band, which, even in the fossil, sometimes is clearly per- 

 ceptible; on the earlier whorls the upper half is occupied by a wider 

 sutural and an anterior luirrower elevated band, separated from each 

 other by a well-marked sulcus; they are crossed obliquely by fine, 

 sharp, regularly spaced elevated lines with wider interspaces, which on 

 the rest of the whorl have a vertical or axial direction to the suture; 

 in the specimen before me about a dozen (partly decollate) whorls exhibit 

 this sculpture, the whole shell being microscopically spirally striated; 

 the sculpture then becomes obsolete, the following four whorls being
