The knotted Haliotis. Shell ovate, spirally ridged, 

 ridges granosely scaled, often alternately the larger, 

 obliquely imdately wrinkled, wTinkles more or less 

 swollen, six holes open ; deep red or scarlet red, ra- 

 diated with yellowish white, or light olive red radiated 

 with gi'een.

This is the most variable species I have met with, and 

 appears to have been gi'eatly misunderstood by authors ; 

 Lamarck confounded it with the H. gigantea, Ms H. tubi- 

 fera ; Philippi ^vith the H. Cimningliumii, whilst Dr. 

 Leach described it in his ' Zoological Miscellany' PL 23, 

 as a new species, under the name of E. ruber. The varia- 

 tions chiefly consist in the spiral ridges being more or less 

 prominently developed, and in the obliquely waved wiinkles 

 being more or less swollen ; in colour the species varies 

 from an uniform deep coral red to a reddish olive, radiated 

 with pale green, as represented in Fig. 27 of the preceding 

 and accompanying plates.

The many-perforated Haliotis. Shell oblong-ovate, 

 rather flesuous, spiral portion of the whorls somewhat 

 elevated ; spii-ally linearly grooved, grooves a little 

 waved, irregular ; holes rather small, nimicrous, ten 

 open; exterior dark-brown, variegated \\\i\i green, 

 interior whitish. 



Hub. ? 



This darkly variegated species, the surface of which is 

 smooth, engi-aved with fine waved spiral Unes, has some- 

 what the form of the H. sangiihiea ; the spii'al portion of 

 the shell being more than usually raised. The holes are 

 niunerous and close set.

The sheep Haliotis. Shell somewhat orbicularly ovate, 

 convexly depressed, spii-e flatly depressed, whorls 

 plicately rayed with swollen \\Tinkles ; holes tubife- 

 rous, five or six open; exterior very beautiftdly mar- 

 bled with orange-red or green, interior silvery.

Hab. New Holland and the PliiUppine Islands. 



An extremely characteristic species, an orange-red mar- 

 bled example of which is very correctly represented by 

 Chemnitz ; neither Lamarck nor Deshayes appear to have 

 been acquainted with it.
