 a precise iletcrniinatiini, Wolf's name lias heen adapted fir the species in 

 preference to that of lia/.niininwsky. 



The t)-pe fiirui cliaracterizi'd hy Wulf has the f;-riiund colonr white, as is 

 evidenced liy the keel and mid-ilorsal line retainin;:' that cnlinir, while the 

 remainder of the animal is almost wliolly lilack, dne to the ililfnsion of tlie 

 lilack markinus. 



The Li mill' iUir,i iiijii var. unhtVur of Bettoni is identical with the type, 

 while LiiiKi.r Inili iji ('olliin^e and L. iiid.ri niim var. /i/cftinsii oidy differ in 

 the white nnd-dorsal line licim;' sidlicd with a slight ochraceons tint and not

Diagnosis. — Extkunai.i.v, L. rliii'nui-ii'Kjer in its tyiiical form is distin- 

 eiiislicd fL'oni /.. inii,riiiiii:< liy its more unif irmly dark colouring, its shorter 

 and stonter tentacles, its coarse and pi'omiuent ruga', and its sharp and 

 well-marked keel, wdiicli usually extends fully half the length of the liody, 

 and sometimes is pereeptihle ipiite to the shield. The shield is typically 

 unicolorous, ami the sol(> distinctly longitudinally ti'ipartite, the outer areas 

 heing black or ileep ash-grey and the miil-area. paler. 



IxTEiiXALrv, the shell is thin and lirittle, almost transparent when fresh, 

 bro.ad and comparatively short; the iienis-sheath is of tolerably e((iial width 

 throughout, not enlarged and stifHy Hexed at the free-end as in L. imi.ri- 

 iiiii.'t. while its retractor arises, according to l)r. Scharfl', between the lieart 

 and the kidney as in L. /I(ini.<, and not behind the kidney as in L. ))i((,ri/tiii.<: 

 the lingual teeth are liroader and also markeilly more cuspidate and eui- 

 br"\'onic in their character; the mandible is smaller and UKU'e delicate, the 

 median beak is not so prominent, and the lower outer nuirgins are distinctly 

 rounded and not rectangular as in L. ii/ii.riiinis. 



liL habits. LiiiiK.r rhhTiii-iiKjcr is more active and less micturnnl than /,. 

 iiKij-iiiiiis. it has a wider range, liotb altitudinally ami gi'ogr.-ipliicalh', and is 

 not so partial to the \-icinity of human dwellings.
