Report Laniell. pi. 1. figs. 1 — le.. the type of which is in the 

 British Mus. of Nat. Hist., is soniewiiat siuiihir. We deemed it 

 advisable to have a comparative examination of our new species 

 with it, and forwarded specimens to Mr. G. B. Sowerhy, who re- 

 plied as follows, 8-1-1 i: — "I examined type of Dosinia deshayesi ; 

 I can understand some of your small ones j^assing for the young 

 of it, but is certainly a distinct sjaecies; its form is different, and 

 it is iiattei-; the ligamentary area is much narrower, and the 

 character of the concentric lamellae different. It is also certainly 

 distinct fiom D. histrio, which runs into t^nrieriafa. I think you 

 may safely describe it as a new species." Further confusion has 

 been added to the puzzle since one of us i-eceived from a South 

 AuvStralian correspondent a St. Vincent Gulf left valve under the 

 name of D. brazieri ; the author was not given, and diligent seai'ch 

 through literature failed to reveal any description under such 

 name : we conclude, therefore, that D. hrazieri is manuscript. 



A medium-sized specimen has been selected for the type. The 

 series studied, ranging from 8 mm. to 45 mm. (paratype), exhibit- 

 ing some slight variation in contour. The colour rays in some 

 specimens are very clearly defined, while in others almost absent. 



We have here to express our many thanks to Mr. F. Chapman 

 for his excellent illustrations of the species.
