E. AREOLATA. Laiii. PL 82, fig. 4T6 ; PI. 83, fig. 525. 



Sliell thinner than E. hffo.-^a, with shoulder more marked and 

 slightly channelled ; umbilicus Avider, open ; same pattern of 

 markings as E. lutosa. but color much darker, blotches more 

 regular, quadrangular, the three reA^olving series more widely 

 separated l)y intervening white spaces. 



Length, 2-25-3-5 inches. 



Ceylon ; China Sea, 14 fathoms. 



E. spirata^ Linn., included this species, as Avell as the one which 

 now bears that name Lamarck separated and defined the two 

 forms. 



E. spiRATA, Lam. PI. 82, figs. 4(5()-4r)8 ; PI. 84, fig. 520. 



Shoulder shari)-edged, deeply channelled ; umbilicus narrow, 



perforated or closed ; epidermis frequently adhering, dark lirowu ; 



coloring a well-defined series of blotches superiorly, below which 



are numerous, rather large transverse or oblique oval spots ; 



some of the latter frequently become confluent into an inferior 



revolving series of irregular or cuneiform markings. 



Length, 2-3 inches. 



Cinjloii ; Philippines, 



Vj. (.'Hrysostoma, Sowb. PI. 82, fig. 469. 



The blotches and spots are both smaller and more numerous 

 than in E. apirata, the form is more oval, the coloring brighter, 



including a carneous aperture and columella. 



Ceylon. 



I separate this from E. spirata with some hesitation. Sowerbj' 

 considers his Pig. 8 of E. spirata to represent this species ; it has 

 the coloration, but the form and markings are of the eharcteristic 

 spirata pattern. Perhaps it would be better regarded as a 

 variet}^ of spirata. 



E. BoRNEENSis, Sowb. PI. 82, fig. 404. 



Spots large, dark chestnut, distributed over the surface with 

 no arrangement into revolving series. Length, 2 inches. 



Borneo. 



Peculiar in the coloring and leopard-like arrangement of the 

 spots.
