THE NAUTILUS. 45 
from the Gulf coast of Matagorda 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-pacifie 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. sp. 
Shell large, solid, strong, with more than 21 slightly rounded 
whorls, color pale yellowish with darker yellow or brown flammule ; 
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 band and pos- 
terior area oblique but nearly straight, those on the anterior area 
coneayely 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 Dall. Ido not find any other species with closely 
similar sculpture.
