Putella aculeata, Reeve, Verco, Trans. Roy. Soc., S.A., 1906, 
vol. xxx., p. 207, and 1912, vol. xxxvi., p. 182. 
Taken on the beach, King George Sound, 10, the largest 
is only 23 mm. by 19 mm.; Ellensbrook, 3, up to 21 mm. 
long; Yallingup, up to 14 mm. It was not taken above Cape 
Naturaliste. The specimens seem to diminish in size and 
scaliness as they go west and north, and are not so large as 
the South Australian shells, which may attain 40 mm. in 
length.

Esperance Bay, 3, up to 17 mm. by 13 mm.; “Albany” 
(Dr. Torr), 20 mm. by 15 mm. by 6% mm.; Yallingup, 6; 
Bunbury, 1. This—which is probably a variant of P. 
ustulata, Reeve—is smaller than the Victorian shell, and 
was not taken above Geographe Bay.

pl. exxxvi., fig. 3; Verco, Trans. Roy. Soc., S.A., 1912, p. 182. 
Taken on the beach at Esperance Bay, 1, very large, 
39 mm. long, 37 mm. wide, and 12 mm. high, and 3 small 
specimens, scaly, with 8 ribs, the anterior splitting early into 
two; at Albany, many, 1 7-ribbed, the others 8-ribbed, out- 
side speckled brown, inside white or brownish-yellow or 
speckled red-brown ; at Ellensbrook, very many, up to 22 mm. 
long and 21 mm. wide and 65 mm. high, mostly 8-ribbed, 
some 7-ribbed, others 9-ribbed, rough and speckled ; on Rott- 
nest Island, several, up to 18 mm. long and 15 mm. wide and 
65 mm. high. 
The reddish-brown specks outside may be arranged in 
radial series on the ribs, or scattered irregularly on the sur- 
face. Internally the spatula may be brown, but generally 
white. There may be a red-brown line along the groove of 
the ribs. No specimens of the polygonal variety, P. chap- 
mant, Tenison-Woods, or of the variety Acmaa albida, 
Tenison-Woods, were found. The typical forms were much 
more numerous and foliaceous than on the eastern shores of 
South Australia. WVaseula-
