Morcu! has shown that Scutus (2) abnormis, G. and H. Nevill,’ from Penang

The Danish Expedition to Siam brought home no specimens of this species. 
Distribution: — “Abundant in Australia” (Sowersy), Victoria (PRITCHARD

A nearly allied species from Mergui has been described by Puitippr under 
the name of Ph. birmanica.* On considering the distribution of P. Australasiae, a 
doubt arises as to the correctness of Mor.et’s determination. 
Pholas (Barnea) sp.? 
The shell of a small Barnea (long. 5 mm.) has been obtained at Koh Kahdat 
which in form and sculpture somewhat resembles B. parva, Penn. On account of 
its small size and bad state of preservation I cannot determine it with any certainty.
