The protoconch (Plate VI. Figs, la-h) of this species is similar 

 to that of L. tortirostris in being somewhat elevated, round! 

 turbinate, and spirally striated ; it is composed of three and a ha 

 to four whorls, and the strife, which are four in number, equi 

 distant, and very pronounced on the last turn, decrease in size 

 on being traced backwards, the top of the larval shell is extremely 

 minute and central. The ornament of the whorls is also much 

 like that of the species just mentioned, but there are only two 

 rows of tubercles, or nodulations, instead of three, on the body- 

 whorl, and seven intervariceal tubercles occur on the posterior 

 peripheral angulation. The specimens from Cape Otway are more 

 elongate than the type found at Muddy Creek, the body-whorl 

 of which is subquadrate. Examples of the young stages of 

 growth are almost inseparable from those of L. tortirostris, and 

 the latter may only be an extreme form of this species.

Closely allied to L. gilhmn, from which it differs in being less 

 gibbose, in having a longer canal, and in the development of 

 distant, bold spiral lineations amongst smaller ones, more especially 

 on the anterior slope of the body-whorl. It is more distorted 

 in the growth than is L. woodsi, the whorls are more compressed
