8 RECORDS OF THE AHSTRAMAN MUSEUM. 



Preserved in Melbourne are four specimens labelled as the types of 

 I'hi/sa pilofnt and registered as 35994-7. The locality is not stated in the 

 description, but these types are labelled "University Ponds." One of 

 tiiese is here illustrated (PI. ii., fig. 19-20), 13 mm. long and 8 mm. broad. 

 In the original account Tenison Woods doubted if P. pilosu was specifically 

 distinct from 1\ riehreriliafo, over which it has page precedence. 1\ piJosa 

 i.s a pale clear i.sabelline colour, whereas V. crehreclliafd, is dark brown. 

 /'. /'//{»»•(< has also a lower spire, a nai'rower forixi and a less developed 

 epidermis than F. crehreciJiata. 



The tj'pe of P. crehreciJiata does not exist under that name in the 

 collection of the Musenm at Melbourne. But 1 have received four 

 specimens, marked " 36028-31, Flnjsa hirsiifa. Ten. Woods, Caulfield." No 

 such species was published by Tenison Woods. The locality, description 

 and comparison of F. crehreciliata suit " hirfiita,'''' exactly. 1 presume, 

 therefore, that the name was changed in course of publication, and that 

 the real t3'pes of ^^crehreciliata'''' are the specimens maiked " /^//•.><'(f/(f." 

 These specimejis are less globose than the oiiginal figure published by 

 Clessin and closely correspond to J'Jnjsa hra;:ieri, Smith, var. major, from 

 the Burnett Rivei', Queensland. There are on the body whoil about 

 thirty-two spirals of fine cilite, decussated by fine close longitudinal 

 lamella^. The latter, as in the case of 7. )ieirco))ihi, rise round the suture 

 into a sort of I'uff or collar. But the epidermis is raiely preserved in so 

 perfect a state. Of the four type specimens, the one which is drawn (PI. 

 ii., fig. 21) has a comparativelj'^ elevated spire, while in the other three 

 the spire is mucli more depiessed. It is 12 mm. long and 8 mm. broad.

Pjdf. Tate notes that in arid legions this species prepares for sipstiv- 

 ation by burrowing into the mud and closing the apei-tuie with a hemi- 

 spheric lid of fine silt.
