SMITH : ON THE GENUS CLEA. 253 



spire was perfect, it being broken and eroded in the old ones. 

 This appears to be characteristic in all the forms, for out of the many 

 specimens examined, only one, and that hardly fully matured, has 

 the spire perfect. It consists of seven whorls, and tapers gradually 

 to a bluntish point, the apex being rather globose. 



2. Clea. HiDALGor (Crosse). 



Quadrasia Hidalgoi, Crosse, Joum. de Conch. 1886, p. 161, pi. viii, 

 figs. 7, la. 



Hob. — Island of Balabac, South of Palawan, Philippines. 



The dimensions given by Crosse are exceeded by both the specimens 

 in the Museum Collection, the larger having a length of 17 '5, the 

 other of 15mm. 



3. Clea Bangtjeyensis, n.sp. 



Tes,t?i C.nidalgoi similis, sed plerumque conspicue major, epidermide 

 olivacea induta, striis spiralibus minus corrugatis sculpta ; apertura 

 antice magis contracta, cferuleo-albida, vel fusccscens ; labrum tenuius, 

 superne latissime et minime profunde sinuatum. Long. 25, diam. 

 13 mm.; apertura 14 longa, 6 lata. Exemplum minor. Long. 20, 

 diam. 9 mm. 



Clea Bangueyensis, n.sp. 



Hah — Banguey Island, off North Borneo and South of Balabac. 



Besides the differences referred to above, I may also point out that 

 this species has seven instead of six whorls, like C. Ilidalgoi, and the 

 apex is white instead of purple-brown. 



The difference in the form of the aperture seems to be constant. 

 In C. Hidalgoi the outer lip is rather saccate in front, whereas in the 

 present species it is contracted. 



4. Clea Bockii, Brot. 



C. Bockii, Brot. — Journ. de Conch. 1881, p. 159, pi. vi, fig. 5. 



Hah. — Paijo, Sumatra. 



Only a single immature specimen was known to Dr. Brot. The 

 species appears to have the same kind of sculpture as that of 

 C. Hidalgoi and C. Bangueyensis.
