174 Dall Diagnoses of New Species of Mollusks.' 



most anterior quite feeble. Length, 20; last whorl, 14; max. diameter, 



7 mm. 



T . Dredged on the west side of the Gulf of California in latitude 31 05', 



in 12 fathoms, muddy bottom. 



. This species has the gloomy color of Strigatella tristis but not tho shell 



characters. The type is No. 109,009, U. "S. National Museum. 



Murex (Oeinebra?) painei sp. nov. 



Shell small, rotund, whitish with five or six whorls; nucleus small, 

 smooth, polished; subsequent whorls strongly sculptured; axial sculpture 

 of numerous (on the penultimate whorl 15) sharp longitudinally wrinkled 

 varices extending from the suture to the canal with wider interspaces and 

 somewhat angular or spinose at the shoulder of the whorl; these varices 

 are usually confluent at the suture with those of the preceeding and fol 

 lowing whorl; spiral sculpture of strong elevated rounded threads, with 

 A Smaller thread in the interspace, somewhat crenulating but not over 

 riding the varices: aperture ovate, the peristome thin, simple, continu 

 ous, projecting; there are no lirations in the aperture, the siphonal 

 fasciole is well marked, the canal short and closed over in front of the 

 aperture, with no discarded canal-spines. Length, 15; length of last 

 whorl, 11; max. diameter 8 mm. 



This pretty little species resembles one of the Austral Trophons in 

 miniature. It cannot be confounded with any other species of the coast. 

 The type is No. 109,306, U. S. National Museum. 



Lunatia draconis sp. nov. 



Shell depressed, solid, cream color, sometimes with a ferruginous or 

 livid tinge, with six whorls: nuclear whorls very small, smooth; later 

 ones with an obscure, nearly obsolete spiral sculpture like flattened-out 

 threads, over which run microscopic, close-set, spiral striae; suture with 

 the whorl in front of it feebly channelled and the excavation bounded by 

 an obsolete thread; top of the whorls flattened, part of the base bordering 

 the umbilicus also flattish, the remainder of the whorl rounded, turgid; 

 umbilicus wide and deep, its walls excavated and closely spirally striated 

 aperture oblique, semi-lunate, outer lip thin, base rounded; the angle 

 where the lip meets the body filled with a smooth white callus, the an. 

 terior angle of the pillar lip also thickened. Height of shell, 51.0; of last 

 whorls 49.0; of aperture, 44.0; max. width of shell, 50.0 mm. 



This species has no close resemblance to any of the other species of 

 the region. The pillar lip is somewhat thickened with a small purplish- 

 brown callus in the perfect shell. The sculpture and the depressed form 

 seem characteristic. From L. lewisi Gould, it is easily separated by its
