I refer a sing-le right valve from Macassar to Sowerby's species. This valve agrées with 

 the descriptions and figures of the species, but differs in the postumbonal région being much 

 shorter than is shown in Sowerby's figure of the T. emarginata^ the umbones in the "Siboga" 

 shell lie in the posterior third of the length. 



Distribution: — T. [T.) emarginata has a wide range in the Indo-Pacific. 



The single valve, which I refer with some doubt to this species, was collected at 

 Macassar (St. 71).

A single left valve in the "Siboga" collection is referred with some doubt to T. (T.) 

 deshayesii., which was described by Hanley from a single valve from the supposed locality 

 Red Sea. The valve in the "Siboga" collection is a half-grown spécimen, and it is not possible 

 to be quite certain ; I figure this spécimen for référence. 



Distribution: — As noted above the single type-shell was supposed to hâve corne from 

 the Red Sea. According to Bertin the single valve in the Paris Muséum, which was purchased 

 from the collection of Wright, also had Red Sea on its label, 



The "Siboga" Expédition collected a single left valve at the Anchorage off Noimini, 

 south coast of Timor (St. 296). 



7. Tellina [Tellina) patagiata sp. nov. (Plate V, figs. 34, 35). 



The following is a description of this new species: — Shell small, subovate, subequilateral; 

 anterior end narrowly rounded, basai margin evenly but slightly arcuate, posterior end feebly
