Tereh^a galvestonensis, n. sp. PI. 3, fig. 5. 



Syii. Terebra, n. sp., Har. , 4th Ann. &c.,p. 121. 



Specific characterization. — General form as indicated by the fig- 

 ure ; apical 3 whorls smooth, remaining 9 or 10. marked as fol- 

 lows : Each whorl with («) about 12 longitudinal costae, narrow- 

 er than the interspaces, (<^) a deeply incised line aboiit one-third 

 way from upper to lower suture, k) a faint spiral line near the 

 base of each whorl ; {d) several spiral lines on the basal portion 

 of the body whorl. The spiral line referred to under (<:) seems to 

 vanish on the penultimate whorl after passing the longitude of 

 the upper margin of the aperture. Two spiral lines, i. e., the one 

 corresponding with the suture and the one just below, are here 

 and elsewhere on the body whorl particularly prominent. The col- 

 umellar fold is plainl}^ biplicate. As in the preceding species the 

 plicae on the different whorls are generally in line, but in contra- 

 distinction to that species the lines in this swing to the right or 

 backwards in passing from apex to base. 



Range in depth. - From 2,387 to 2,871 feet. 



CONUS.

Conus punctictdatjis. PI. 3, fig. 6. 



Syn. C. p2inctiailatiis Hwass, Enc. Meth.- Fide Reeve. 



There are several so-called species of Conus on either side of the 

 Isthmus of Panama that are closely allied to this. The good spec- 

 imens are nearly alwa^^'S immature; they are generally more strong- 

 ly grooved at base than tj^pical puricticulatus is, hence they re- 

 semble closely ^j'^^^e^?!!.^ ; but the general form, crenulations and 

 fragments of adult shells indicate a closer relationship with the 

 former. 



Range /;« depth. — From 2,236 to 2,920 feet.
