1914 Bulinus crebreciliatus (Ten. Woods). Chapman, Mem. Nat. Mus., 
Melb., No. 5, p. 58, pi. 1, fig. 1. 
1917 Isodora hainesii (Tryon) var. crebreciliata (Ten. Woods). Hedley, 
Rec. Aust. Mus., xii. No. 1, p. 7, pi. 2, fig. 21. 
Size of Type, — Length, 15 mm. ; breadth, 7 mm. 
Localities. — Caulfield (Type) ; Brighton (Nat. Mus., 
Melb.) ; Horsham (W. Kershaw) ; Melbourne (E. H. Mat- 
thews) ; Sandringham. 
Vernacular Name. — The Ciliated Pond-Snail. 
Observations. — Hedley gives a good figure of the presumed 
type of Physa crebreciliata l^en. Woods and makes the fol- 
lowing comments: “The type of P. crebreciliata does not 
exist under that name in the collection of the Museum at 
Melbourne. But I have received four specimens, marked 
‘36028-31, Physa hirsuta Ten. Woods, Caulfield.’ No such 
species was published by Tenison Woods. The locality, des- 
cription and comparison of P. crebreciliata suit ‘hirsuta^ 
exactly. I presume, therefore, that the name was changed 
in course of publication, and that the real types of ^ crebre- 
ciliata’ are the specimens marked Oiirsuta.’ These specimens 
are less globose than the original figure published by Clessin 
and closely correspond to Physa brazieri Smith var. major, 
from the Burnett River, Queensland. There are on the body 
whorl about thirty-two spirals of fine ciliae, decussated by 
fine, close longitudinal lamellae. The latter, as in the case of 
7. new combi, rise round the suture into a sort of ruff, or 
collar. But the epidermis is rarely preserved in so perfect 
a state. Of the four type specimens, the one which is drawn 
(PI. II, Pig. 21) has a comparatively elevated spire, while 
in the other three the spire is much more depressed. It is 
12 mm. long and 8 mm. broad.” 
Careful study of the type specimens leads me to concur 
with Hedley ’s remarks, but I do not agree with him in 
regarding the form as a variety of hamesii Tryon.
