 figs. 24 — 27. 



A single somewhat worn shell dredged at St. 99, agrées very well with Hedley's description 

 and figures of Gafrarium catillus. The "Siboga" shell is not so "angled dorsally" and the 

 ribbing on the surface of the valves is not so prominent, but thèse slight différences are due 

 more to âge and the worn condition of the "Sibog-a" shell. I figure this shell. 



Distribution : — Gafrarium catillus was found by Hedley to be a common species off 

 the Hope Island in 5 — 10 fathoms of water. 



The single "Siboga" spécimen was, as noted above, dredged at the Anchorage off North 

 Ubian (St. 99, 16 — 23 mètres).

Dall and Jukes-Browne hâve discussed at length the divisions and subdivisions of the 

 genus Paphia Roding. I agrée in the main with Dall, but with Jukes-Browne hâve adopted 

 the subgenus Amygdala Romer in préférence to Ruditapes Chiamenti. The génotype is Paphia 

 ala papilionis Roding. 



The subgenera represented in the "Siboga" collection are: — Paphia s. s., Tapes Megerle — 

 type Paphia {Tapes) literata (Linn.); Protapes Dall ^) — type Paphia {Protapes') gallus (Gmelin); 

 Paratapes Stoliczka ^) — type Paphia {Paratapes) textile (Gmelin) and Amygdala ^) Romer — 

 type Paphia [Amygdala) decussata (Linn.).
