Plate XXXVIII. 



Species 120. (Mus. Cuming.)

 conoided, apice subcentrali, obtnso, radiatim costatd, 

 costis tumidiiisciilis, obtusis, intcrsiitiis suhexcavath, 

 fortiter striatis ; fuscescente-albidd, costis albis, intiis

The guttehed Limpet. Shell oblong-ovate, rather ele- 

 vately conoid, apex nearly central, obtuse, radiately 

 ribbed, ribs rather swollen, obtuse, interstices rather 

 excavated, strongly striated ; browuish-whitc, ribs 

 white, interior transparent-white. 



llab. ? 



Chiefly distinguished by its oblong-oval form and pro- 

 minent radiating ribs, which are somewhat swollen and 



Species 121. (ilus. Cuming.) 



Patella fenestkata. Pat. testa ovatd, antice siibat- 

 tenuatd, tenuiculd, depresso-conoided, apiee pi'ominente, 

 auhobtuso, radiatim dense teuuistriatd, siriis subundu- 

 latis ; viresceiite, ci?iereo-oIivaceo undique tenuisshm 

 tessellato-macalatd, iiitiis cceridescente-ciiiered, margine 

 lata, nigro. 



The windowed Limpet. Shell ovate, a little attenuated 

 in front, rather thin, depressly conoid, apex promi- 

 nent, rather obtuse, radiately densely finely striated, 

 stria3 a little waved ; greenish, finely tessellately 

 mottled with ash-olive, interior bluish-ash, with a 

 broad black border. 



Nuttall, Jay's Catalogue of Shells, p. 38. 



Hab. Upper California. 



The colouring of this species is peculiar, the outer sur- 

 face being densely mottled with a very fine network of 

 ash-olive upon a greenish ground, whilst the interior is 

 characterized by a broad black border. 



Species 122. (Mus. Cuming.) 



Patella puncturata. Pat. testd sicbqaadrato-ovatd, 

 apice ceutrali, snhohtuso, radiatim costald, costis in-e- 

 gularibiis, nunc distinctis, nunc siibobsciiris, liris con- 

 centricis fere obsoletis caiicellatis, super costis squa- 

 mato-pustidatis ; opaco-alhd, punctis sangnineis 2'aiicis 

 promiscue aspersd, iiitus opaco-albd. 



The kose-dotied Limpet. Shell somewhat squarely 



ovate, apex central, rather obtuse, radiately ribbed, 

 ribs irregular, sometimes distinct, sometimes rather 

 obscure, cancellated with nearly obsolete concentric 

 ridges, squamately pustuled on the ribs; opake- 

 white, promiscuously sprinkled with a few blood-red 

 dots, interior opake-white. 

 LAMARCK,Anim. sans vert. (Deshayes' edit.) vol. vii. p. 537. 

 Hab. Honduras; Dyson. 



This appears to be the species imperfectly described 

 by Lamarck under the above name from Barbadoes. Its 

 chief characteristic is the sprinkling of blood-rose dots 

 upon an opake-white ground, and squamately pustuled 

 ribs, which are more or less worn. 



Species 123. (Mus. Cuming.) 



Patella achates. Pat. testd ovatd, teiiidcidd, convexo- 

 depressd, radiatim dense striald, striis liic illic tenue 

 funiculatis ; intense nigrd, radiis aJhis fiilguratis irre- 

 gidariter variegatd, intus cteridescente, margine late 

 jiigro-variegato. 



The agate Limpet. Shell ovate, rather thin, convexly 

 depressed, radiately densely striated, striae here and 

 there finely corded ; intense black, irregularly va- 

 riegated with lightning-marked white rays, interior 

 bluish, with a broad black variegated border. 



Hub. ? 



A strikingly characteristic species in respect of painting, 

 densely rayed with fine corded striffi. 



Species 124. (Mus. Cuming.) 



Patella Dunkeri. Pat. testd ovatd, conoided, latera- 

 liter suhcompressd, apice antice inclinato, subunci- 

 nato, tenuiculd, siihpellucidd, radiatim dense elevato- 

 striafd, interstitiis minutissime cancellatis ; ciuereo- 

 corned, pallide radiatd. 



Bunker's Limpet. Shell ovate, conoid, a little com- 

 pressed at the sides, apex inclined anteriorly, slightly 

 hooked, rather thin, subpellucid, radiately densely 

 elevately striated, interstices very minutely cancel- 

 lated ; ash-horny, faintly rayed. 



Krauss, Siidafric. Moll. p. 55. pi. 3. f. 14. 



Hab. Port Natal. 



A delicately rayed ash-homy subtransparent shell, ela- 

 borately sculptured with raised striae, the interstices be- 

 tween which are very minutely cancellated.
