A fine specimen from the Morelet collection from Dr. Wel- 

 witsch hearing' the above name is before me and from it the 

 above description was drawn. Its comparative smoothness, 

 and richer color distinguish it from S. Icf'sii, if these charac- 

 ters are constant. There are no teeth in the shell I have de- 

 scribed.

The original description is not accessible to me at the pres- 

 ent time. Germain, (1. c, 1907), remarks: "The Spatha tawai, 

 according to the types in the Museum of Paris, is a shell which 

 differs from Spatha chaiciana only by its much smaller and 

 noticably more compressed form and by its clearer epidermis, 

 which is a magnificent, very brilliant green. It is extremely 

 probable that the two species are synonymous and that S. taivai 

 is only the immature form of .9. chaiziana." 



Spatha inne.'^i Pallary. 



"The Spatha cailliaitdi von Martens is a large species, which 

 has been well figured by Cailliaud (Atlas II, pi. 60. fig. 12),. 

 under the name of Anodonta rnbcns and by Jickeli, pi. viii, 

 fig. I. 



The name of Anodonta rnbcns was applied by Lamarck to a 

 form from Senegal, different from the Egyptian species and 

 for tliis reason M. von JNfartens gave to the species figured by 

 Cailliaud the name of that traveller. We have not found \xr
