BUCCINUM tetragonum. 



TAB. CCCCXIV.— /^. 1. 



Spec. Char. Squareish, ovate, pointed, cos« 

 tated ; costae crossed by four large and 

 several small ridges; aperture oblong; lip 

 toothed within. 



A. THICK rather square rugged looking shell ; the large 

 ridges divide the surface between the costas into cells, 

 that are crossed by the smaller intermediate ridges : it 

 is probably when perfect, covered with concave scales ; 

 their remains give it much the aspect of a Murex : the 

 beak is short, and but slightly curved ; the teeth in the 

 lip are about seven, they are blunt. 



But one specimen of this species is in Mr. Sowerby'a 

 cabinet ; it was kindly placed there by Mrs. Cobbold, 

 who found it near Ipswich. 



BUCCINUM incrassatum; 



TAB. CCCCXIV.— ^V. 2. 



Spec. Char. Thick ; ovate, pointed, rugged, 

 with about five caiinsB, the uppermost 

 largest; aperture oval; lip obscurely fur- 

 rowed within. 



The few nearly smooth, large, principal carinse, with 

 very slight indications of lesser ones between them, and 

 the weii^-ht of this shell wdl always make it easily known : 

 the obscure furrows in the lip form obtuse teeth be- 

 tween them, and are opposite the carinas ; the deep and 

 distant lines of growth make the surface rugged. 



An abundance of this very distinct species in all 

 stages of growth, has been found by the Rev. G. R. 

 Leathes in Suffolk, and a liberal supply sent for figur-
