THE NAUTILUS. 45 



from the Gulf coast of Matagortla Island, which could not be iden- 

 tified with any described species. Subsequently Mr. Mitchell sent 

 the upper part of the spire of another specimen in rather better pre- 

 servation. 



A specimen in perfect condition in the hands of a lighthouse 

 keeper was heard of, and a description was deferred in the hope that 

 this shell might be obtained for the purpose. After a long delay 

 the loan of it was secured, but it proved to be merely a common 

 Indo-pacific shell and not the Texan one. The following description 

 is therefore drawn up from the two known specimens in the hope 

 that, attention being thus drawn to it, some one may succeed in 

 securing fresh specimens. 



Terebra Texana n. ^>. 



Shell large, solid, strong, with more than 21 slightly rounded 

 whorls, color pale yellowish with darker yellow or brown flammulas ; 

 sculpture of two revolving grooves one on each side of a peripheral 

 slightly raised band, a little narrower than the areas between it and 

 the sutures ; the whorls are crossed by numerous small flexuous rib- 

 lets in harmony with the lines cf growth, those on the baud and pos- 

 terior area oblique but nearly straight, those on the anterior area 

 concavely arcuate, these are stronger on the spire and more feeble 

 on the last whorl or two ; suture appressed, distinct ; last whorl 

 moderately rounded ; pillar twisted, strong, with a sharp revolving 

 keel and a feeble revolving ridge above it, continuing up the axis 

 of the shell, but not visible in the aperture where the pillar seems 

 only callous and rounded ; siphonal notch and fasciole strong. 

 Length (of 21 whorls) 137 mm., diameter of last whorl 24 mm. 



This is the first typical Terebra known from the tropical waters 

 of eastern America, and is much stouter and larger than the T. 

 (Subula) floridana Ball. I do not find any other species with closely 

 similar sculpture.
