MARINULA. 
Marinula, King, Zool. Journ. vy. p. 343 (1832); H. & A. Adams, Gen. Recent Moll. ii. p: 246 ; 
Pfeiffer, Monogr. Auric. p- 59. 
Shell oval, imperforate, thick, without spiral sculpture ; aperture rather large, broad, 
with two parietal folds and a smaller columellar one beneath them; outer margin of 
the aperture straight, simple. Foot of the animal not divided by a transverse furrow. 
Spread throughout the tropical and subtropical shores of both hemispheres—the 
typical species on the western coast of South America, on stones and rocks at high- 
water mark. 
1. Marinula acuta. 
Auricula acuta, d’Orbigny, in Guérin’s Mag. Zool. 1835, p.23'; Voy, Amér. mérid., Moll. p. 826, 
t. 42. figg. 4-6°; C. B. Adams, Ann. Lyc. Nat. Hist N, York, v. p. 432 (1852)*; Carpenter,

Marinula acuta, Pfeiffer, Monogr. Auric. p. 62°; Catal. Auric. Brit. Mus. p. 45°. 
Fusiform-oblong, faintly striate, brown, with some darker streaks ; two strong parietal folds, the columellar 
fold tooth-like ; outer margin of the aperture straight. 
Long. 123, diam. 54 ; apert. long. 73 millim. 
Hab. 8. Panama: Panama, under stones near high-water mark (C. B. Adams *4). 
Ecuador: Guayaquil, near brackish water (Fontaine 1256), 
In its general aspect this species resembles the European members of the genus 
Alexia, but differs from them in the straight outer margin. J. (Auricula) recluziana, 
Petit (P. Z. S. 1842, p. 201), from Tumaco, on the coast of Colombia, possibly belongs 
to this species rather than to WM. pepita, King, from Chile and Chiloe, with which it 
was united by Pfeiffer (loc. cit.). 
BLAUNERIA.
