SIMPULUM. l IT 



T. WATEBHOUSEI, Ad. and Ang. PL 9, fig. 62. 



Yellowish brown, somewhat tinged with olive; white within 

 the aperture. Length, 2'25 inches. 



8. Australia. 



The spire is proportionally shorter, the shoulder of the whorls 

 not so well marked ; whorls more rounded than in last species. 

 Epidermis squamately pilose. 



T. BOLTENIANUS, A. Ad. 



Allied to T. Spengleri, but smaller, more ponderous, and 

 without varices. The j^oung shells are peculiarly inflated, and 

 banded inside with dark purple ridges. Length, 2 inches. 



Not figured. I have not seen it. 



T. BARTHELEMYI, Bernardi. PL 10, fig. 69. 



Yellowish white, the transverse grooves darker; brownish 

 within the aperture. Length, 5-5 inches. 



S. Australia, among rocks at low tide. 



Evidently very closely allied to T. Spengleri, of which it will 

 very probably prove to be an overgrown form, living amidst 

 uncongenial surroundings. 



T. LABIOSUS, Wood. PL 9, figs. 64-68. 



Shouldered ; encircled by revolving ribs, each of which is 

 bi-sulcate, so as to divide the rib into three ; decussated by 

 almost equally strong longitudinal costae ; canal usually short. 

 Yellowish to dark chestnut-brown, sometimes light-banded ; 

 aperture and columella white. Length, 1 inch. 



Japan, Philippines, Mauritius, Australia, West Indies. 



The numerous specimens before me, from various West Indian 

 localities, are not distinguishable from Australian examples. T. 

 Loroisii, Petit (fig. 66), has no distinctive characters. T. 

 Strangei, A. Ad. and Ang. (fig. 6T), from Australia, has less 

 shoulder and longer canal than the typical form, but I have 

 before me a West Indian specimen which closely mimics the 

 figure of that species. T. orientalis, Nevill (fig. 68), from the 

 Indian Ocean, has a somewhat longer canal, but does not other- 

 wise differ from the typical labiosus. These may be considered 

 varieties by those who are fond of minute distinctions.
