Edg. Smith (loc. cit.) thinks that the present species "on account of the absence 

 of lateral teeth and the oblique sculpture" must be referred to Psammobia, but I 

 am convinced that he is wrong in this; the absence of the lateral teeth being typical 

 of the subgenus Peronaea, and the oblique sculpture being found in so many other 

 species of Tellina.

It seems to me that Philippi has good reason for doubting whether Chemnitz's 

 lacunosa "from Guinea" is identical with the ''lacunosa from China" of later authors; 

 therefore, I have adopted his name coarctata for the latter form. Unfortunately, it 

 is very probable that Chemnitz's original specimen of lacunosa no longer exists, at 

 any rate it is not to be found in the Zoological Museum of the University of Copen- 

 hagen, so actual comparison is impossible; but as Chemnitz's figure and description 

 present many characteristic points which are not to be found in coarctata, 1 think 

 we have here two distinct species. 



It is no doubt due to a mistake that Spengler' gives "East India" as the 

 locality of his T. ephippium. His original specimens are in the Zoological Museum 

 of the University of Copenhagen, but on the label, in his own handwriting, no 

 locality is given. On comparing Spengler's original specimens of T. ephippium 

 with specimens of Say's intastriata (= T. Gruneri, Phil.^) it is seen that these species 

 are absolutely identical, and as Spengler's name has the priority. Say's intastriata 

 and Philippi's Gruneri should consequently be regarded only as synonyms of
