of European specimens of Mod. burbata L. ; bul as the material at my disposal for 

 comparison, was insufficient to decide this question, I sent some specimens to Pro- 

 fessor Eu. V. Martens. He informed me that he considered them to be: "pluinescens, 

 Dunker; Ci.essin beschreibt u. bildet sie ab, aber unter dem Namen tumescens, 

 wahrscheinlich nur aus Irrthum (falsches Lesen)." The confusion introduced by 

 Clessin into science by his "Monographs" in the new edition of Martini & Chemnitz: 

 "Conchylien Cabinet" is much to be regretted. Edg. Smith mentions, in his report 

 on "Alert's" zoological results, ' a Modiola sp. (taken at Port Molle) "remarkably like 

 the European M.barbata" it is probably the present species.

Ed. v. Martens' supposes that Mod. Riimphii, Phil, is synonymous with M. 

 Pbilippinariim, Hani. In the specimens from the Gulf of Siam the interior is 

 whitely-iridescent. 



Modiola Evansi, Smith. 



Modiola evansi, Edg. Smith, Journ. of Concliology, X, 1903. p. 368. 



Tale Nawi in Lower Siam (Rich. Evans). 



This species does not occur in the collections made by the Danish Expedition. 



Edg. Smith says with regard to the locality from which this species has been 

 taken : "This semi-lake is probably brackish water, being almost enclosed from the 

 sea, and having several rivers and streams running into it."
