126 GARRETT: CATALOGUE OF CYPR^ID^. 



Half-grown specimens are olive-grey or bluish-grey, with 

 raised white papillcC, without the intervening ridges ; base 

 and teeth white, the latter shorter than in adults. 



72. T. oryza, Lam. Has the same range and station as the 

 preceding species. The Polynesian shells, which are not un- 

 common, are smaller than East Indian examples. 



The animal is light snuff-brown, frecked with diluted 

 white and creamy-yellow. The upper surface of the foot is 

 reticulately veined with the latter color. The siphon has a 

 terminal fringe. 



73. T. (Pustularia) staphylaea, L. This species seems to 



be somewhat scarce, and has the same range and station as 

 the two preceding. 



The few examples before rne differ slightly in shape and 

 convexity of the dorsal region. The color varies from livid 

 to brown, and all have the ends tinged with brownish-yellow. 

 The basal ridges are rather large, and extend across the face 

 of the shell. 



The animal has a thin, elongate-oblong foot, acutely 

 rounded behind, slightly auriculate in front. Tentacles long 

 and slender, bearing the eyes on -small basal enlargements. 

 The short siphon is fringed. Mantle processes large, rather 

 crowded, tentaculiform, with a few dendritic ones intermixed. 

 The creeping disk is pale purple-brown, lighter in front, and 

 delicately veined with a darker shade. Siphon and the upper 

 surface of the foot blackish-brown, the mantle deep brown, 

 which, with the upper surface of the foot, is minutely dotted 

 with white. 



74. T. sphaerula, Mighels. A few examples gathered in beach- 



sand at the Society, Paumotu, and Sandwich Islands. 



Mr. Pease, in his ' Synonymy of Marine Gasteropoda 

 inhabiting Polynesia,' referred this species to Gray's T. glolwsa, 

 and suggested that it will prove to be a variety of T. oryza.
