770 TROCHUS. 



Inhabits the coasts of Fernambuca. Favanne. 



This shell is said to be about the size of a filbert, with eight 

 whirls rising above each other in the manner of a Chinese 

 Pagoda, and white tinged with flesh-colour. Bonanni's, 

 Petiver's, and Favanne's, are magnified figures. Both Chem- 

 nitz and Gmelin have quoted Knorr, iv. t. 25. f. 6, but it 

 appears different, and is quoted by Favanne for his Sabot 

 tourne, 



STRiGOSUS. 24. Shell pyramidal, transversely stri- 

 ated, with the whirls flattish, and slightly tu- 

 mid at the margin.

Inhabits the coasts of Morocco. Chemnitz. 



This shell appears by Chemnitz's figure to be about five lines 

 long, and nearly equally broad, and of a yellowish white co- 

 lour variegated with red, and the summit black ; the tumid 

 margin is spotted with red in fig. 1651, but it is by no means 

 clear that fig. 1650 belongs to the same species, and Schroe- 

 ter has arranged them separately. 



DUBius. 25. Shell pyramidal, with transverse gra- 

 nulated striae, and the margin of the whirls 

 nodulous and vaulted.

The latter of the above-mentioned figures is about ten lines 

 long and nine broad, but the former is much smaller, and 

 narrower in proportion, and Chemnitz's description is so in- 

 definite that it is impossible to ascertain whether Schroeter 

 is right in placing them as separate species ; the colour is 

 whitish variegated with chestnut. T. Pyramis of Born is 

 different, and is the T. Obeliscus of Gmelin. 



DEPRESsus. 26. Shell depressed, whitish, radiated 

 with red, and the apex red ; whirls gut with 

 a belt of moniliform dots.
