CHEMNITZ’s original specimens of T. inflata (in the Zoological Museum of the 
University of Copenhagen) are very large and rather thick-valved,! but they exactly 
agree with REEve’s figure of T. striatula, Lam., and with the specimens from the Gulf 
of Siam. V. Bertin, who has had an opportunity of consulting LAMARck’s original 
specimens of striatula, in his “Révision” gives both REEve’s and HANLEy’s (SOWERBY) 
striatula as synonyms of the present species. ROMER (in MARTINI u. CHEMNITZ, Conchyl. 
Cabin.) is mistaken with regard to his inflata, Ch., neither his description nor his 
figures agree with CHEMNITz’s species;? BERTIN also says that ROMER is wrong in 
reporting striatula, Lam., to be young specimens of the West Indian 7. fausta, Pult. The 
specimens from the Gulf of Siam, all of which are rather small and consequently 
thin-valved, entirely agree with ReEve’s figure of striatula. It appears as if the 
convexity of the valves varies somewhat in this species; thus, in a specimen from 
the Gulf of Siam, measuring 25 mm. in breadth and 21 mm. in height, the thick- 
ness is 10°5 mm., while in an individual from Suez,* of the same breadth and 
height, it is only 7 mm. 
Tellina languida, dg. Smith, is very closely related to the present species.

1 CHEMNITz's figure is not good and is partially misleading. 
* Romer is hard to be understood, when his figure of inflata (pl. 15, figs. 1—3) is compared with 
the figure of striatula by Hanvey (pl. 61, fig. 175), which he gives as a synonym; the two figures do 
not resemble each other in the least. 
8 In the Zoological Museum of the University of Copenhagen, received from L. VaitLanr, who has 
determined it as T. truncata, Hanl. (Journ. de Conchyl., 1865, p.121, No. 79).
