Malea camura Brown and Pilsbry. Proc. Acad. Nat. Sci. Phila., p. 

 356, 1911- 



We have a large series, some of the younger shells being 

 very like Guppy's immature, Jamaican type. The nearest living 

 ally and descendant is the West Coast M. ringens Swainson. 

 Some of our shells with fewer spiral bands look like M. promum, 

 but the characters of the aperture are more those of ringens. A 

 mutation from Zone F, Rio Gurabo has closer ribs, about 20. 



M. camura occurs at B owden and is doubtfully reported 

 from Gatun. 



Localities. — Zones F, G, Rio Gurabo at Los Quemados; 

 Bluffs 2 and 3 (Very abundant, all sizes), Cercado de Mao. 



Malea, species indet. 



A very large species, no mm. in diameter, nearly twice 

 as large as M. camura, was found in Zone I, Rio Cana at Cai- 

 mito, but is too imperfect to describe. 



Genus Pyrula Lamarck 



Pyrula Pilsbryi Smith 

 Pyrula pilsbryi Smith, Proc. Acad. Nat. Sci. Phila., p. 213, fig., 1 1907. 



In this species the surface between the primary spirals is 

 flat, not concave as in P. carbasea Guppy from the Caroni Series, 

 Trinidad. The type locality of P. Pilsbryi is Bowden. 



Locality. — (Exp'd '16). Zone I, Rio Cana at Caimito. 



Genus Ovula Bruguiere 

 Ovula {Neosimnia) Wise- Woodcs, n. sp. 

 Plate 22, Figure 17 



Shell resembling O. spelta in outline, smooth except for fine, 

 wavy spirals near the extremities and delicate longitudinal 

 growth-lines; outer lip markedly arcuate, bordered by a callus 

 band; dorsal surface convex, with a slight but obvious hump 

 most apparent on the latter half of the body whorl; columella 

 with one very strong posterior plication; posterior canal sharply
