570 NOTES ON SPECIES OF CYPR.EA, 



Fig. 3, PL xxi., is that of a specimen measuring from the 

 syphonal end of the posterior apertural notch 25 mm; it is 15 mm. 

 wide, and 13 mm. high from base to the most prominent part of 

 the dorsum, which is of a deep chocolate colour; there is a slight 

 trace of two bands of a darker colour across the dorsum; the 

 shell is more pyriform in shape than either of the preceding 

 examples; spire sunk; a small dorsal sulcus, the spots along which 

 are not so large or numerous, and very few are seen in looking 

 down on the dorsum; on the right columellar margin there are 

 30 strong teeth running straight into the aperture; on the left 

 side the teeth are very fine and not seen on the base, which is of 

 a bluish colour. 



Cyp. angustata, Gray, var. Mayi, C. E. Beddome (Plate xxi. 

 figs. 4-7). — I can pick out four varieties from many examples of 

 this species, and think it best to describe and figure them. 

 Fig. 4 is that of a specimen measuring from the syphonal end 

 to the posterior apertural notch 24 mm., 16 mm. wide and 13 ram. 

 high from base to most prominent part of the dorsum, which is 

 of a rich orange colour; there are two distinct chocolate bands 

 across the dorsum, and above the spire some spots that form a 

 third band; a slight dorsal sulcus with a few chocolate spots on 

 it; the spots on the other side are few, about sixteen in number; 

 on the right columellar margin there are 26 teeth, not so strong 

 as in the typical group, and those on the left are fine and not 

 seen on the base, which is whiter than in the former. 



Fig. 5, PI. xxi., represents a specimen of about the same 

 measurements as fig. 4; dorsum dull salmon colour, two brown 

 bands across dorsum, and between the spii-e and one of the bands 

 with a raised line of growth. 



Fig. 6, PI. xxi., shows a rather young specimen, but I think it 

 worthy of notice; it measures from the syphonal end of the 

 posterior apertural notch 25 mm., 16 mm. wide and 12 mm. high; 

 dorsum of a dull chocolate colour which extends down the left 

 side of the shell into the aperture; three distinct bands across the 

 dorsum ; spire region tinged with orange ; a very slight dorsal
