Plate II. 



Species 4. (Mus. Cuming.) 



Haliotis varia. Hal. testa ovato-oblongd, depresso-con- 

 vexd, spird humili ; oblique tumido-nodosd, spiraliter 

 erehiliratd, liris valde irregularibus, foraminibus senis 

 pervils ,- viridi aut olivaceo-fusco luteoque diversimodo 

 radiatim variegatd, intus argented. 



The variegated Haliotis. SheU ovately oblong, de- 

 pressly convex, spii-e low, obliquely tumidly nodose, 

 spu'aUy closely ridged, ridges very UTCgidar, sis holes

Hab. Philippine Islands ; Cuming. 



A good distinguishing mark in this species are the curious 

 swollen nodides, ranging across the shell in oblique waves, 

 though sometimes a little obscure. The variegated yellow 

 and oUve-green colour is mostly disposed in alternate 

 enlarging stripes striking out from the nucleus of the spire. 

 Mr. Cuming found the H. varia abundantly distributed 

 throughout the Philippine Islands. 



Species 5. (Mus. Cuming.) 



Haliotis rubicunda. Hal. testa suborbiculari-ovatd, 

 teuuiciild, medio concavo-depressd, latere siimtro fricos- 

 tato, costd externa tuberculatd, scabrosd, mediam tu- 

 biferd, perforatd, foraminibus quinis senisve perviis, 

 infernd tumidd, compiciid, rtigoso-striatd, lamellis tenui- 

 bus undato-striatis erectis inter spiram ei costam. inter- 

 nam coucentrice dkpositis ; extus rvfescente aut olivaceo 

 viridique variegatd, intus pulcherrime irridescente. 



The red-tinged Haliotis. SheU somewhat orbicu- 

 lai'ly ovate, rather thin, concavely depressed in the 

 middle, left side three-ribbed, the outer rib tubercu- 

 lated and scabrous, the middle rib tubiferous and 

 perforated, six to seven of the perforations open, the 

 inner rib swollen, conspicuous, roughly striated, with 



thin lameUaa concentrically an-anged between the spire 



and the imier rib ; exterior reddish or variegated olive 



and gi-een, interior very beautifidly iiTidescent.

 The structm-e and syimnetrical an-angement of this spe- 

 cies is tiidy elegant ; and liighly characteristic of the 

 beautifid natui'al productions of the countiy of which it is 

 an inhabitant. 



Species 6. (Mus. Cuming.) 



Haliotis rufescens. Hal. testa ovatd, convexo-depressd, 

 crassiusculd, spiraliter liratd, liris minntis irregula- 

 ribus ; oblique undaio-pUcatd, plicis grandibns tumidis ; 

 foraminibus subamplis, tuiulosis, quaternis tantum per- 

 viis ; extus corallo-rubrd saturatd, intus irridescente, 

 lahri dextri limbo intus corallo-rubro. 



The coral-red Haliotis. SheU ovate convexly de- 

 pressed, rather thick, spiraUy ridged, ridges minute, 

 iiTegvdar ; obliquely wave-pUcated, plaits large, swol- 

 len ; perforations rather large, tubulous, four only 

 open ; outside deep coral-red, inside irridescent, 

 inner edge of the right Up coral red. 



SwAiNSON, Appendix to BUgh Catalogue, p. 2. 



Hab. Ceylon ; Dr. Sibbald. 



A fine dark coral-red species growing in large obUque 

 swoUen imdidating waves. " In proportion as the back of 

 this species is worn down," says Mr. Swainson " the 

 colour becomes of a bright red," an observation very signi- 

 ficant of its real character.
