204 TURBO. 



T. QUADRISERIATUS Anton, 1839. PI. 44, fig. 79. 



This form is known to me only by a short description and 

 Philippi's figure, which I have reproduced. I am inclined to believe 

 it a form of T. castaneus, although I have seen no specimen of that 

 species approaching very nearly to it. Anton says that it has "4? 

 bauschige Windungen, letzte mit vier Reihen stunipfer Tuberkeln 

 besetzt, die iibrigen bloss quergestreift," etc. 



West Indies (Anton.) 



T. SQUAMIGER Reeve, 1842. PI. 49, fig. 43. 



Shell globosely ovate, imperforate, suture excavated ; whorls 5-6, 

 convex, carinate, the last ventricose, with erect tubercles at the 

 suture, "spirally armed throughout with scales, upper and lower 

 scales much larger ; pale green, dotted and variegated with reddish 

 brown, interior silvery." Alt. 27, diam. 26 mill. 



W. coast Mexico and Central America : Galapagos. 



I have not seen this species. It may perhaps belong in Callopowa, 

 but also resembles a very roughly sculptured T. castaneus. 



T. MOLTKIAXUS Gmel., 1788. PI. 49, figs. 44. 45. 



Shell ovate-conic, solid, imperforate ; w r horls 5, convex, subcari- 

 nate above, striate, irregularly lirate and bearing a series of rather 

 elongated radiating tubercles below the suture ; shoulder tuberculate, 

 median portion of body-whorl with several less prominent nodose 

 carinse ; aperture oval ; columella callous, arched, deflected and 

 somewhat produced below ; color whitish with broad revolving 

 hands of dull red. Alt. 40, diam. 35 mill. 



West Coast of Mexico. 



This is undoubtedly the cochlea lunar is moltkiana etc. of Chemnitz, 

 Turbo moltkianus Gmelin. I have been on the point of placing this 

 and the next species in Callopoma. The resemblance to T. saxosus 

 is striking; but it differs in its less sloping shoulder and in the 

 absence of the columellar groove. The operculum is unknown. 



T. SUBCASTANEUS Pilsbry, 1888. PL 46, figs 10, 11. 



Shell ovate-pointed, imperforate, grayish ; spire conic, acute ; 

 whorls 5, marked with revolving series of tubercles, subangulate 

 and nodulose at shoulder; suture well impressed, with a series of 

 coarse radiating corrugations below it ; aperture rounded, slightly 

 exceeding half the length of shell, white within ; columella arched, 

 slightly dilated at base. Alt. 23, diam. 19 mill. 



Habitat unknown.
