There is however no wa}^ of distinguishing the form represented 

 by fig. I and that by fig. 2, they pass from one to the other 

 with imperceptible gradations. The specimen Aldrich called 

 F. tombigbeensis is of the rugose type and has a tendency to 

 present crenules or nodules at the intersedlion of the spiral and 

 longitudinal lines. This feature however, in a large quantity 

 of material, is found to be not of specific value. Aldrich re- 

 marks : "The type specimen has unfortunately lost its canal, 

 but a younger specimen supplied the description. Younger 

 .specimens have the whorls more carinated than in the figured 

 type." Unfortunately the "younger specimen" referred to is 

 a Pleurotoma (pi. 2, fig. 4). The young of this Fiisus are not 

 particularly carinate.

 fig- 3- 



Harris' original description. — "Size and general form of the 

 .shell as indicated by the figure ; whorls 8 or 9 ; embryonic 3 

 smooth ; others marked by from 8 to 10 sharp, flattened peri- 

 pheral spines, at whose base, or immediately at the suture, a 

 subordinate .series of spines occurs on the larger whorls ; canal 

 nearly closed, long, straight ; labial callus thin. At first sight 

 this seemed like a large, well-formed F. mohri, but on comparing 

 details it was found to be very distindl."
