Za GUTTUBNIUM. 



T. TRiPUs, Lam. PI. 12, fig. 93. 



Pale j'^ellowish brown, lighter colored on the revolving ribs ; 

 white or pale blush within the aperture. Length, 2 to 3 inches. 



Indian Ocean, China. 



Like T. caudatus, this species has canaliculate sutures. 



T. VESPACEUS, Lam. PI. 12, figsi 94-100. 



Yery finel3^ granulated ; dorsal tubercles large, giving the 

 shell a somewhat hump-backed appearance. Yellowish white, 

 marbled and banded with brown. Length, 1-5 inches. 



Australia, Viti Isles, Sandwich Isles. (Pease). West Indies. (Swift). 



The above localities are all authentic. The typical full-grown 

 shell is that described b}^ Reeve as T. Thersites (figs. 99, 100), a 

 form occurring both in the West Indian and Polynesian localities. 

 T. vespaceus was described from a smaller, though perhaps full- 

 grown shell, probably a more stunted growth. !r.(?/on_7a/».s(fig. 96), 

 and T. gracilis (fig. 97), of Reeve, are of somewhat more graceful 

 form and have a longer canal ; the latter is represented in the 

 collection of the Philada. Academy by specimens from St. Croix, 

 W. I., and from the Yiti Isles. 



T. TENUiLiRATUs, Lischkc. PI. 42, fig. 105. 



Shell varying from light to dark brown, white within the 

 aperture. Yarices four ; whorls nine, of which the first four 

 are embryonal and small. Length, 40 mill. 



Japan; Sandwich Isles, ( W. H. Pease). 



I copy the figure of Dr. Lischke, which represents the unique 

 and decidedly imperfect specimen from which he described his 

 species. 



T. AMicTus, Reeve. PI. 40, fig. 188. 



Whitish, with a soft, sparingly bristled epidermis. 



Length, 1*4 inches. Philippines. 



I do not know the species. The figure somewhat resembles 

 Uupleiira caudata. 



T. EXARATUS, Reeve. Pi. 12, figs. 102, 104. 



Shell with two varices ; the whorls flat shouldered ; revolving 

 ridges duplicate. Whitish, variegated or banded Avith brown, or 

 brown with a white median band. Length, 1-75 inches. 



Australia.
