It is to be regretted that this fine shell did not arrive 

 into my hands prior to the publication of my ' Historical 

 Account of the Genus Latirus ' in the Memoirs and 

 Proceedings of the Society in the early part of this year 

 (1891), for it exceeds in size any of the eleven species 

 of Latirus and Peristernia described in that monograph 

 for the first time. The shell is rufous-brown, elegantly 

 fusiform, turreted, somewhat solid, possessed of ten whorls, 

 each regularly ornamented with thick longitudinal ribs, 

 crossed transversely (excepting at the sutures, where the 

 shell is smooth) with equidistant filamentous lira. The 

 canal is produced, the mouth distinctly ribbed within, 

 columella four plaited, white. There is some little resem- 

 blance to Fasciolaria filamentosa (Lam.) in miniature, or, 

 among the Latiri. to L. Gracilis (Reeve), and especially
