Genus Latirus, 2>77 



(Lam.) van Knorrii (Desh.) the animal was dark red, 

 of the colour of raw beef, and I believe all the animals 

 of this genus that have been examined, are of that appear- 

 ance. So far as I recollect, however, Fasciolaria distans 

 (Lam.), which I found at Charleston, So. Carolina, commonly, 

 did not possess this peculiarity, but was of a grey mottled 

 colour, as also F, tulipa (Lam.), and its transversely ribbed 

 var. Scheepmakeri (Dh.) which I found commonly on the 

 coral reefs in the south. Good representations of the 

 animals of this family may be found in Adams Gen. Recent 

 Mollusca^ Vol. III., pi. xvi., f i. Latirus {Fasciolaria) 

 lignariiis (L.) copied from Chiagni Poli. L. turritus (Quoy 

 and Gaimard) Voy, Astrolabe Moll, pi. xxxv., fig. 14.

Mr. Cooke writes that the following species have passed 

 under the critical observation of himself and Mr. H. M. 

 Gwatkin, of Cambridge, and conclusively proved to be 

 Latiriy Peristernice^ or Fasciolarice, by their dentition.

Many of these identifications have never as yet been 

 published. 



It is, naturally, almost impossible that during the life- 

 time of this generation, we can hope to obtain accurate 

 knowledge of the dentition of all the species included in these
