The chief characteristic of this species is the simple, not 

 zigzag or angulate streaks. It varies from the typical form 

 (figs. 27, 31) to a more slender and elongate shape, which 

 has been named bridouxi (fig. 28). The latter approaches 

 L. martensi var. elongata. 



Another form, differing from typical rectistrigata in the 

 wider base, deeper suture, etc., has been named L. burtoniana 

 by Grandidier (Bull. Soc. Malac. France, ii, p. 160, 1885). 

 See pi. 33, fig. 24.
