TESTA oblonga, turrita ; Aperturd obloiiga, obli- 

 qua^ lahio externo sinuoso^ incrassato, revoliito, 

 basi oblique truricaco; lahio interno incrassato, 

 expanse, partem inferiorem aiifractus ultimi et 

 €olumellam tegente. 



An oblong turrited univalve, with an obliquely placed ob- 

 long aperture, outer lip thickened and turned outward, 

 with two sinuosities, one placed in an oblique direction, 

 close to the base of the shell, and forming a sort of shallow 

 canal, the other, rather above the centre of the lip, and less 

 conspicuous ; inner lip thickened, spreading ov er the lower 

 part of the last volution and the Columella. 



By the above characters the shells of this Genus will 

 easily be distinguished from those of Buccinum and Murex, 

 the only two genera it could possibly be confounded with. 

 The Murex stramineus of Gmel. may be considered as the 

 Generic Type, which shell is however very distinct from 

 Murex, and does not agree with Linne's character of that 

 Genus. 



Lamarck established the Struthiolaria : apparently only 

 one species was known to him, it is what we have called 

 Struthiolaria straminea in our plate ; had it not already been 

 published under this specific name, we should gladly have 

 adopted the more expressive one of nodulosa, by which 

 Lamarck has designated it ; a second, which we have called 

 inermis, has lately been added : both are from the coast of 

 New Zealand. S» inermis may be distinguished from S, stra-
