108 PHTLLONOTUS. 



ally so elsewhere, otherwise tuberculate. Whitish or light 

 brownish, the lines and spines darker in color. 



Length, 1 to 2 '5 inches. West Africa. 



This species is usually represented by specimens of the smaller 

 dimension ; it will probably prove to be the young of M. Beckii 

 or M. turbinatus. 



M. TRUNCULUS, L. PI. 23, fig. 205; pi. 29, figs. 258-261. 



The commonest species of Southern Europe, being found 

 everywhere throughout the Mediterranean Sea as well as from 

 the southern Atlantic coast of France to Senegal and the Canary 

 Islands; also Red Sea? Fossil, as far back as the miocene. 

 Varies much in form, as shown by our figures. Usually light 

 brown, with about three broad purplish bands which are very 

 distinctly marked within the aperture. 



Length, about 3 inches. 



M. turbinatus, Lam., and M. Beckii, Phil., are analogous species 

 from the West Coast of Africa. 



M. ZELANDICUS, Quoy and Gaim. Pi. 29, fig. 268. 



Pyriform, spire short, canal rather long ; with five rows of 

 varices armed with sharp spines, of which those round the shoul- 

 der and the lower part of the body-whorl are much longer than 

 the others. Yellowish-brown. Length, 2 inches. 



Cook's Straits, New Zealand. 



I copy one of the original figures, including the animal. It 

 does not appear to resemble any of its congeners closely. 



M. CRISTATUS, Brocchi. PL 29, figs. 263, 267. 



Shell whitish or yellowish, frequently darker, or chocolate 

 colored within the aperture. Length, T5 inches. 



Mediterranean, Atlantic Coasts of /So. Spain to Senegal ; Madeira. 

 Littoral to 40 fathoms. Fossil ; miocene and pliocene of So. 



Europe. 



M. Blainvillei, Payr., (fig. 265), is merely a small variety of 

 this species. The columella is somewhat tuberculate towards the 

 base and the lip has a few large teeth within ; these characters in 

 connection with the less spiny, but more frondose varices will 

 distinguish it from the nearly related M. hexagonus. Lam. M. 

 serotinus, A. Ad., is, according to Sowerby, a synonym.
