M arte si a striata {Linn.). 



Hub. — Tongaat, Natal. Boring in floating seeds of an 

 Indian species of Barringtonia (B. speciosa). 



I have as yet seen only young specimens of this species 

 from South Africa. 



The M arte si a falcata of Sowerby's ' Marine Shells of S. 

 Africa/ p. .54, is also the early stage of this species. He 

 quotes it as of Gray, and refers to his father's monograph in 

 the ' Conchologia Iconica.' '^I'he shell there described^ as 

 Pholas falcata Gray, MS., Brit. Mus. (!), and figured PI. 

 XII, fig. 51, is cuneiform is Soij, but whether it is the same 

 species as the Pholas falcata of Wood- is very doubtful. 



Xylotrya stutchburyi {Soiferlnj). PI. VIII, figs. 8-8 h. 



Teredo stutchburyi (Leach MSS.) Soiccrhy, 'Conch. 

 Icon./ vol. XX, PI. II, figs. 5 a-c. 



Teredo skutschburyi (sic!) Learli ; Clessin, 'Conch. 

 Cab./ Pholadea, p. 68, PI. XVI, figs. 14-16 (after Sowerby). 



Hab. — Port Klizabeth and Durban (H. Burnup) ; Sumati-a 

 (Coll. Leach in Brit. Mus.) ; Pulo Bidang, North of Penang 

 (Skeat Coll. in Brit. Mus.) ; C'hristmas Island, Indian Ocean 

 (Brit. Mus.). 



The figures in the 'Conchologia Iconica' are most crude, and 

 do not give the least idea of the characters of this species. The 

 sculpture on the central area of the valves is finer than that 

 of the anterior area ; indeed, it is so fine that it is invisilde, 

 excepting under a very powerful lens. It is then seen that 

 the longitudinal minute threads are excessively finely 

 granose. 



The form of the anterior area differs entirely from the 

 figures of it, 5 a, 5 h, and in realit}- is much moi-e nearly repre- 

 by fig. 11a on PI. III. 



' The locality given, " Hudson's Bay." should have been Hondin-as. as 

 Avi'ittcn on the Museum tablet. 



- ' General Conchology.' p. 84. pi. xvi. figs. 5-7 (1815) ; 'Index Test," 

 p. 9. pi. ii. fig. 8 (1S25)."
