Locality.-Taken on the beach at MacDonnell, Rivoli, 
and Guichen Bays; many dredged alive in 5 fathoms, St. 
Vincent Gulf, and in 20 fathoms Backstairs Passage; valves 
dredged in Spencer Gulf, and also in 40 and 150 fathoms off 
Beachport, and one valve in 130 fathoms off Cape Jaffa. 
Nucula beachportensis, sp. nov. Pl. xxvii, fig. 3./3, al” ; 
Oval-trigonal, moderately solid. Umbos prominent, in- 
flated, slightly opisthogyre, incurved. Teeth about thirteen 
anterior, solid and curved; six posterior. Fossa for the inter- 
nal cartilage rather small, directed forwards and inwards. 
Dorsal border very slightly excavate just behind the fossa, 
then convex, then straight to the posterior inferior angle; 
ventral border with a uniform curve, joining with a smaller 
curve the anterior dorsal border, which has a very slight 
convex arcuation, and is about twice as long as the posterior. 
Inner ventral margin minutely crenulate. 
Sculpture.—Smooth, but for obsolete rounded concen- 
tric strie at irregular distances, and scanty microscopic 
radial striz. 
Dimensions.—Umbo-ventral, 4°6 mm.; antero-posterior, 
4-9 mm. 
Locality.—Dredged off Beachport, 40 fathoms, 1 perfect 
(type), 2 valves; in 100 fathoms, 1; 150 fathoms, 2; 200 
fathoms, 1; off Cape Jafia in 130 fathoms, 1; 300 fathoms, 
6; all dead. 
Diagnosis.—It is very like N’. micans, Angas, but is a 
larger shell, is smoother, is not so uniformly rounded behind, 
but is truncated or straight from the end of the hinge to the 
ventral border, and the crenulations are fewer and more valid.
