6 E. C. Joshua : 



There are five typical specimens of this species in the collec- 

 tion of the National Museum. Melbourne. They are presumed ta 

 have been collected in Victorian waters, but exactly when and 

 where is not indicated. Whitelegge (20) records the animal from 

 Port. Jackson, X.S.W. 



COLOCHIRUS DOLIOLUM (Pallas). 



For localities and synonymy, see 

 Erwe Willy (8). 



Young specimens of this Colochirus are frequently found from 

 the shore down to al)Out five or ten fathoms. Tlieir spiculation 

 exactly agrees with the mature form, but the dark, brown, pig- 

 mented areas, which occur in the older animals, are only repre- 

 sented by very faint yellow bands, which rapidly lose their colour 

 in spirits. 



GEXUS PSOLIDIUM. 



PsoLiDiUM CONVERGENS Perrler.

 Locality. — Flinders. 



I secured three specimens of this apparently rare species at 

 Flinders; they agreed well with Perrier's description (18). 



GENUS CAUDINA. 

 Caudina chilensis (J. Muller).

 Clark (3). 



Localities.— We^teA-u\)0\-t Bay, Mordialloc. 



The above localities furnished two specimens which, though dif- 

 fering widely in appearance, I assign to this species. The larger, 

 picked up after a storm at Mordialloc, measures 100 x 40 mm. ; 

 .it tapers sharply posteriorly, but cannot be described as caudate, 

 colour yellow, blotched with brownish pink ; TJie spirules are inoi-e 

 massive than those typical of chil('>isi-'<. the lioles being smaller, 

 and the cross being frequently lost by fusion with the disc. The 

 whole ossicle seems to have undergone a process of hypertrophy. 



The other specimen, from Westernport Bay. is fairly typical. 

 Some temptation existed to regard these two specimens as belong- 

 ing to distinct species, but fortunately the writer has recently 

 had an opportunity of examining a collection of over forty speci-
