'he rose Harp. Shell ovate, thin, ventricose, pale 

 yellowish brown, ornamented with large, square, 

 bright rose spots ranging round the shell in three in- 

 terrupted bands ; ribs flat, irregular, sometimes very 

 broad, sometimes very narrow and rather obsolete, 

 interstices rather irregularly painted with delicate 

 curved lines confusedly articulated together ; mar- 

 gin crenated.

db. Senegal, and north of the Gambia, Africa (found 

 in sand, in deep water). 



This delicate and much-admired species is allied in 

 me respects to the Harpa nobilis ; the ribs are however 

 ore feebly developed, and they are not crossed with 

 e same vivid black lines. The rose spots are more 

 mndant and characteristic, and of a much more delicate 

 lour. 



In the specimen represented at Fig. 8 a, from the very 

 oice collection of Mr. Stainforth, the ribs are unusually 

 oad.

arpa crenata. Harp, testd ovatd, supernc tumidd, 

 caruleo-grised, maculis grandibus perpaucis sangui- 

 neo-purpureis irregulariter aspersd ; costis nunc latis, 

 nunc aiigustissimis, superne muricatis, interstitiis lineis 



eximiis, arcuatis, nebuloso-articulatis, rarii pictd .

The crenated Harp. Shell ovate, swollen round the 

 upper part, bluish grey, irregularly sprinkled with a 

 very few large crimson-purple spots; ribs -run- 

 times broad, sometimes very narrow, armed with 

 three or four prickly tubercles near the top, inter- 

 stices variously painted with delicate curved lines 

 confusedly articulated together; margin crenated.

Variety /3. (Fig. 9 *.) 



Testa elongatior, costis planis, latioribus. 

 Shell more elongated, ribs flat and broader. 

 Hah. Acapulco, Mexico (found in sandy mud in deep 

 water) ; Cuming. 



This shell, which has a very strongly crenated lip, may 

 be separated with great propriety as a distinct species 

 from the Harpa rosea, and I quite agree with Mr. Swain- 

 son, M. Lesson and others, in arranging it as such. The 

 lip of the Harpa rosea is also crenated, and it has cer- 

 tainly a veiy strong affinity with the Harpa crenata in 

 all respects excepting colour ; the deep blue-grey is pe- 

 culiar to the latter, and when it is remembered that thev 

 inhabit very different localities, I think a specific di- 

 stinction should be allotted to them if one can possibly 

 be defined. 



The assertion of a modern writer, whose monograph 

 of this genus is not a very creditable one, that the 

 Harpa rosea is the young of the Harpa crenata, is per- 

 fectly absurd ; it is no uncommon thing to see either in 

 different stages of growth, and I have represented an old 

 Harpa rosea, Fig. 8 d, with a young Harpa crenata. Fig. 

 9 c, in order to remove this impression.
