54 DESCRIPTION OF NEW 



Remarks. — Tlie form of this species is more attenuate than usual with the clavate forms. 

 It has about ten whorls; those above the body whorl being disposed to be both plicate 

 and striate. Towards the apex they are all thickly striate. On all the specimens before 

 me, on the lower whorls, there are irregular oblique striae, somewhat similar to those on 

 the M. Ocoeiinsis, (Nobis,) which give them a malleate character. On the upper margin 

 of the whorls, along the sutures, there is usually an indistinct light line. The outer lip is 

 broken.

Reinarks. — This is a very remarkable species, and among the largest of our Melanise. 

 In form and size it is allied to annuUfera,, Con., but may easily be distinguished by its more 

 numerous strise, its reddish colour, and the form of its aperture, which is more open. In 

 the Brumbyi there is an angle in the middle of the whorl, which gives the aperture a 

 rhomboidal form. The columella is rufous and the channel whitish. The apex of each 

 of them being broken, the number of whorls cannot be correctly ascertained. I should 

 suppose there were at least ten. Some of the specimens here are beautifully granulate 

 between the stria;. The aperture is not quite one-fourth the length of the shell. Along 

 the suture, on the upper part of the whorl, there is a line of a lighter colour than the 

 other part. 



I dedicate this species to Prof. R. T. Brumby, who has done so much in bringing to 

 light the interesting shells of Alabama.

Remarks. — I have about a dozen of this species, which is very distinct from any 

 with which I am acquainted. The locality I am uncertain about, the label being by 

 some accident lost. I believe it comes from Tennessee, but am not certain. Its very 

 marked character of a screw, or rather the end of a gimlet, strikes one at once. In 

 most species there is a thread-like line above the carina and several below. The carina
