viction regarding its affinities. It is held to be a Pleurotomid 

 by Try on and Cossmann, but some other authors apparently 

 consider it more closely affiliated with Buccinum. In Dono- 

 vania the shell is very small in size, generally slender, with 

 four or five body whorls which are evenly and feebly convex 

 from suture to suture and without trace of fasciolar surface. 

 The sculpture is strong and relatively very coarse, either 

 simply clathrate or with rounded ribs, the coarse spiral lyrae 

 mutually equal and some four in number. The aperture is 

 short, from distinctly less to decidedly more than a third as 

 long as the shell and is broadly oval. The canal is extremely 

 short but rather well differentiated and the embryo is rela- 

 tively large in size, hemispherical, smooth and paucispiral. 

 It inhabits the present European seas. 



It is stated by Cossmann that the genus J^esaea, of Eisso, 

 which, being preoccupied, was named Chauvetia by Monteio- 

 sato,is synonymous with Donovania and thatthei^oZmaea,of 

 Monterosato, founded wpon Buccinum Ze/e^vrez Marav., is also 

 synonymous, but, as Cossmann states — after Tryon — that 

 Donovania in its broad sense occurs not only in the Medi- 

 terranean but in Japan, the East Indies and the Island of St. 

 Paul, it is probable that there are a few really distinct genera 

 confounded under that name, which lack of material and 

 complete literature of the subject prevent me from investigat- 

 ing at present. Donovania minima, the type of the genus, 

 according to Bellardi and Cossmann, occurs also in the 

 Italian Pliocene and Post-pliocene strata, being described 

 from the former under the name Lachesis brunnea Donov. 

 The association of Donovania with Bela, which has been 

 suggested, appears to me to be wholly unwarranted.

This enormous complex, one of the largest of the Gastro- 

 pod series, is composed of moderately small to minute species, 

 occupying diversified environments throughout the globe, but 

 particularly abundant in the Indo-Pacific region and wonder- 

 fully developed near New Caledonia. In comparison with 

 known living forms, the fossils are very few in number and
