The coloration is brown with the base paler, the sculpture of 
numerous rough radials being overrun by small granules, this 
granulation covering the apex and persisting throughout, being 
only a little modified on the base. 
The type figured is a medium sized shell measuring: diameter 
18 mm.; height 17 mm.: a larger dead shell measures 24 mm. by 
23 mm.

Orthotvpe Helix bordaensis Angas. 
Shells varying from conical to flattened hellcolds, with rugose 
plicate surface, som.etimes granulose, periphery subkeeled or 
acutely keeled, mouth simple, umbilicus usually narrow, always 
open. 
This series seems very unlike Xanthomelon, and suggests 
that the anatomical data need revision as to their value. Nothing 
much more unlike the type of Xanthomelon than Glyptorhagada 
could be produced. 
Key to Species. 
Shell with spire flattened (abnormal in type), periphery sub- 
keeled, sculpture of irregular wavy riblets, umbilicus 
narrow deep, outer lip thin, columella slightly re- 
flected clydonigera. 
Shell with spire less elevated, sculpture coarser, umbilicus 
small almost hidden by reflected columella, outer 
lip reflected, mouth almost continuous herberti. 
Shell with spire a little elevated, periphery semikeeled, um- 
bilicus narrow, partly hidden, ribs less numerous 
than in preceding silveri. 
Shell with spire depressed, periphery more keeled, ribs wavy 
more irregular, base rounded, columella rather 
straight, umbilicus not hidden kooringensis'
