together; between the orifices and the basal rim four strong cords can be counted. 
Columella plate flattened, broad, hiding all the previous whorls. Interior 
yellowish pearl, shining. Length 28 mm.; breadth 18-5 mm. This was also 
collected at Michaelmas Cay. 
Family TROCHID/E. 
The species of this family, be they large or small, are always attractive, 
and much of interest was found at Michaelmas Cay as many species grouped 
around T. maculatus Linne were collected. Of the six species Iledley allotted to 
Troehus— calcar atus, fenestratus , hexagon its, maculatus , nil otic us , and ob discus 
— one, lie sag onus, must be rejected as it is based on a misinterpretation only. 
Tr or Juts niloticus must be called Roehia nilotica, or, perhaps better, Roehia 
pagodas , while T. fenestratus and T. ob cliscus are transferred to Teclus. In 
addition to T. macula las and T. calcaral us, some other species were determined 
as true Troehus, thus T. obesus Reeve ( Conch. Icon, xiii, pi. xjii, sp. and f. 75, 
Dee. 1861; loc. ?) and T. erebrigranatus Reeve (loc, cit. ph xv, sp. and f. 89, 
1861; loc. ?), and a third certainly appeared to agree with T. fastigiatus A. 
Adams (Proc. Zool. Soc., 1851, 150; Reeve, loc. cit. pi. xv, sp. and f. 87, 1861 ; 
loc. ?) . 
Genus CALL I OSTO M A . 
I have already pointed out that the southern shells so classed have little 
relation with the true Pakearetic Calliostoma, and this conclusion has been con- 
firmed by study of the raduke by Thiele. I suggested they seemed nearer to 
Thalotia and this appears to be correct According to a label in the Australian 
Museum, Medley’s C. trepidum is stated to be identical with the earlier deception 
of Smith. There are more species of this little group which may be distinguished 
by the new generic name of Ltd if auto r. Medley ’s shell being type. Further, the 
species known as C. arm ease Watson seems to represent the southern Thalotia 
very closely, and may be separated with the new generic name of CalthaJotia, 
Watson’s species being type. Another new generic name. Talchrasiclc, is here 
proposed for, A stele septemrium Melvill & Btanden, and Medley’s Calliostoma 
specAosum, which may not be that of A. Adams, appears congeneric. These 
species will be elucidated with figures later, as there are some very beautiful 
species to be described, and all the species are localised in distribution. 
To the species of (dan cuius must be added C. gatliffi Tomlin (Proc. Malac. 
Soc. (Loud.) vol. xvi, p. 24, fig. in text, April 1924: West Australia, Coral Sea). 
Gibbula townsendi Sowerby must be expunged, as Mr. Medley told me it was 
included purely in error. 
The species allotted to Monilea need redistribution, as that generic name 
needs rejection. Under Talopia can be placed colli fern, le/ntiginosa, and belcher i 
(since added by Medley); nuclea belongs to Rossiteria; lifuann to Talopena , 
while glaphyrella might be placed there, though not quite typical; pud ib an da 
should be omitted at present as the specimens here so named do not belong to the 
species; for henniana I introduce the new name Conotalopia, and tropicalis may 
be included here temporarily. 
At Michaelmas Gay many specimens were collected of the shell known as 
Minolia agapeta Melvill & Standen, but whose correct name 1 have shown to be 
Monilea apicina Gould, and for which 1 introduce the new generic name 
Parminolia, naming this species as type. Probably more than one species is 
known under that name. There are shells which occurred numerously and had
