typical form. Leiifith -V-') iiiiii., l)readth 17 min. ; as fcjmparL'd with 

 length 41 iiiiu., brcadtli 22 iiini., in the original description. 



This is tlie more us\ial foini at the Muddy Creek and l\iver 

 Mm- ray Cliffs sections. 



Type of tliis vai'iety fioni .Muddy Creek and in my own colhHtion. 



6. VOLUTA AVELDII, \ ar ANGUSTIOK, var uov. (PI. XX., Fig.s. 4, 5). 



Obs. — This form is rather common at Table Cape, and nuiy be 

 characterised by its relative narrowness, acute slope of the spire 

 whorls, continued down to the angulation of the body whorl, and 

 by the very faint development of nodes. Length 30 mm., breadth 

 14 mm. 



Type of variety in my osvn collection.

 XXX., figs. 4. 4a. 

 Obs. — McCoy illustrates well in his prodromus some of the varia- 

 tion to which this species is liable, and marks c)ff figure 3 as the 

 average form, figure 2 as a remarkably short-spired vai-iety. and 

 figure 4 the long-spired variety. McCoy's short-spired variety 

 certainly occurs at Table Cape, and the form Avhich has been named 

 stolida by Johnston seems to me but anotlici' robust variation of tliis 

 species. The type of V. xfrnpliodon, McCoy, is in the Xational 

 Museum, Melbourne. l)nr the type of Y. stolida. Johnston, is not 

 in the Hobart Museum, and is pi-obably in Mi-. Johnston's private 

 collection. If the latter had been visiljle a more definite compari- 

 son could have been made, and greater surety given. There is no 

 representative of this s])ecies in the Hobart Mnscnm.

Obs. — In conformity with the treatment meted out to o\ii- other 



common volutes in having varietal names for extreme forms, it is 



only fair to call tlir specially-conoidal form by a distinctive name, 



viz., hrevhjt'ivd . 'i'his form occurs at Tal)l(' Cape wliilst tlie very
