Obs. — Of the Victorian representatives, this species alone belongs 

 td the group possessed of articulated pallets, a grouping adopted by 

 Quatrefages and others. They are extremely fragile. Surmounted 

 on a thin, cylindrical stalk is a lamina or blade composed of imbri- 

 cating and pectinate joints, flat on the inner area, and rounder on 

 the outer. Much variation exists in respect to the number of articu- 

 lations and their approach to one another; however, the general 

 character is apparent, and the pallet serves as a ready means of 

 recognition. On the assumption that the pallet of T . fragilis, Tate* 

 was incomplete, and represented the basal joint of Gdlobates saulii, 

 Wright. Mr. Hedley. P.L.S.N.S.W., 1898. p. 95, states: " The 

 apparent difference in the pallets is due to the fracture of the 

 specimens figured, wherein all joints but the basal one have been 

 snapped off," and, therefore, he reduced it to a synonym, this 

 synonymy in turn being accepted by Tate and May, Pritehard and 

 Gatliff, and Suter. We are much indebted to Dr. J. C. Verco for 

 sending to us for examination the type pallet of T . fragilis, Tate. 

 This enables us to pronounce the validity of Tate's species. Here- 

 with a figure of the type is presented, which, consistent with the 

 author's description, "small shelly clavate pallets, the stalk much 

 attenuated, the enlarged, somewhat compressed upper portion 

 crowned with a cartilaginous crust, which has a projecting horn at 

 each end," cannot he confused with a basal joint. 



Possibly the authentic specimens seen by Mr. Hedley may not be 

 identical with the type sent to us. 



The articulations of the pallet of T. saulii are formed oil a con- 

 tinuing stalk, whilst in T. fragilis the stalk does not continue 

 beyond the base, but is merged into it; this fact, in our opinion. 

 conclusively proves that the pallet of the latter cannot be a fractured 

 pallet of T. saulii.
