 convex than the right, the former bearing 10 coarse costse, the latter 

 about 25, between which, on both valves, appear numerous finer 

 riblets ; auriculae very unequal, the anterior large, descending in 

 a curve, the posterior comparatively small, forming approximately an 

 obtuse-angled triangle, both sculptured with scaly riblets ; colour

The nearest ally of this handsome species appears to be Pecten Ic^tus 

 from Japan, from which, however, it differs in being somewhat more 

 orbicular, in the greater number of the costae in both valves, on which 

 the scales are much smaller and further apart, and in the shape of 

 the auriculae, the anterior being considerably more curved, while the 

 posterior descends more abruptly and without the curve noticeable in 

 P. Icetus. 



97. Mttilus smaragdinus, Chem. 



A few specimens picked up on an island in the Canton estuary, 

 washed up after the great typhoon of November, 1900.
