12 SIMPULUM. 



The animal is of a light straw -yellow, covered with black spots, 

 which become distant and larger upon the head ; tentacles long 

 and black. The name olearium Linn, appears in the 12th edition 

 to apply here partially, .but it is not the olearium of the 10th 

 edition nor of Born nor (Imelin. It is the Mitrc.r roxtafm* of 

 Born (not Gmelin), and partkenopu* of von Sails. The current 

 identification of the Linnean name is so well established that, 

 however ill it may accord with tact, it seems preferable to 

 retain it. 



T. PILEARIS, Linn. PI. (>, figs. 31-30 ; PI. 7, figs. 38-39. 



Yellowish brown, with occasionally darker (and sometimes 

 white) revolving bands; aperture and columella orange-red to 

 blood-red, with white plications ; epidermis thin, hairy and 

 bristly, light olive color. Length, 2 to 5 inches. 



Red Sea, Seychelles, Natal, China, Japan, Australia, Philippines, 



Sandwich Isles, Florida, West Indies, Brazil. 



Kobelt distinguishes T. Martimanus ( Veliei Calkins, fig. 36). 

 T. aquatilis Reeve, (fig. 34), and T. intermedium Pease, (fig 35), 

 as varieties ; but I cannot so regard them, as 1 find no characters 

 by which to separate them. T. vestitus Hinds, (figs. 38, 39), 

 from the west coast of Central America, has normally, a shorter 

 spire and more inflated body-whorl, is smoother, darker in color, 

 the lip and columella between the plications dark chocolate ; yet 

 the intermediate stages between this and the typical pilearis 

 make a continuous series. 



T. RUBECULA. Linn. PL 7, fig. 40. 



Lemon to orange color, or orange-red, with a light lemon or 

 white revolving band on the middle of the body whorl, and w r hite 

 blotches on the varices ; lip and columella same color as outer 

 surface, with the plications white. Length, 1 to 2 inches. 



Red Sea ; Nicobar Isles ; Philippines ; Central Pacific ; 



Sandwich Isles; St. Thomas, W. I. 



The last locality is upon the authority of a dredged specimen 

 in the Swift Collection, now in the museum of the Philada. 

 Acad. For this specimen Morch made a variety occidentale, but 

 it has no distinctive characters.
