purple-brown spots. Sculpture of coarse and irregular concentric 

 wrinkles and sulci, the umbonal region smooth. Interior of a peculiar 

 Isabella tint. Pallial sinus wide and extending to or a trifle beyond 

 the middle of the shell's length. :\Iuscle scars well impressed. Hinge 

 spisuloid, with the bearing faces of the lateral teeth vertically crenu- 

 late. 



Length 58, alt. 32.5, diam. 19 mm. 



Fukura, Awaji. Type No. 86,313, A. N. S. P., from No. 1,561 of 

 Mr. Hirase's collection. 



Compared with S. aspersa Sowb.,^ this species differs in proportions, 

 being longer and narrower. A specimen of S. aspersa before me meas- 

 ures°length 53, alt. 33, diam. 18.5 mm., the altitude being therefore 

 contained about 1.6 times in the length. The beaks are correctly 

 stated by Reeve to be at the anterior third. The palhal sinus is much 

 longer than in S. bernardi, nearly three-fifths the length of the shell. 

 The lateral teeth are longer in *S'. bernardi. The external sculpture is 

 conspicuously unlike in the two species. It is named in honor of the 

 late M. Felix Bernard. 

 Cytherea crispata amica n. subsp. PI. XXXIX, 6gs. 10, 11. 



Shell shortly ovate, ventricose, rather thin, the beaks at about the 

 anterior third of its length. Pale buff, marked with three indistinct 

 diverging brown rays, the color confined chiefly to the lamellae, and 

 with some scattered spots, and narrow oblique stripes on each side of 

 the beaks. The beaks are rather full; the lunule cordate and defined 

 by sunken lines; no escutcheon is defined on the right valve, but a 

 depression marks it in the left. The immersed ligament is narrowly 

 lanceolate. The anterior end is rounded, the posterior subtruncate. 

 Sculpture of very numerous rounded radial riblets, wider than their 

 intervals, and undivided throughout. These are crossed by many thin 

 erect concentric lamellse. The upper side of each one is fluted, the 

 ridges corresponding to intervals of the radial riblets, while the lower 

 side is much more deeply fluted, a narrow buttress arising from each 

 radial riblet. The interior is white, the pallial sinus short and ascend- 

 ing, rounded at the end. Muscle impressions and pahial line are very 

 faintly indicated. The anterior and median cardinal teeth are simple 

 and rather slender in the right valve, the posterior tooth deeply bifid. 

 In the left valve the anterior cardinal is simple compressed and high, 

 the middle one wide and deeply bifid, the posterior slender and lamellar. 

 A curved ridge extends from the hinge-plate partly around the anterior
