SIMPULUM. 17 



T. Waterhousei, Ad. and Ang. PI. 9, fig. 62. 



Yellowish brown, somewhat tinged with olive ; white within 



the aperture. Length, 2'25 inches. 



S. Australia. 



The spire is proportionally shorter, the shoulder of the whorls 

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

 Epidermis squamatel}^ pilose. 



T. BOLTENIANUS, A. Ad. 



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

 without varices. The young 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 transvei'se grooves darker ; brownish 

 within the aperture. Length, 5-5 inches. 



S. Australia, among rocks at low tide. 



Evidentl}' 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. PI. 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 costse ; 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. 

 Sti^angei, A. Ad. and Ang. (fig. 61), 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. orievtaliH, Nevill (fig. 6S), 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.
