The above description is taken from a shell deprived of its epi- 

 dermis, and I have only seen one with the epidermis on, and that one 

 is not in good condition. The epidermis is dirty white. On the an- 

 terior part of the fourth whorl a band of longitudinal brown dashes, 

 occurring at regular intervals, extends far upon the whorl from near 

 the suture. A similar band skirts the anterior part of the body- 

 whorl, which is belted with two whitish bands, the uppermost rather 

 below the middle, and is greenish at the base. Upon plunging the 

 shell into water the upper epidermis disappears, and exposes the 

 ground-colour ; but the greenish epidermis remains unchanged. The 

 aperture of the shell almost looks as if it had been curtailed arti- 

 ficially, so suddenly does it terminate. 



Bulinus Alberti. Bui. testa pyramidali, anfractibus sex, lineis 



incrementi obliquis creberrime striatd, anfractu ultimo cateros vix 



cequante, apice acuto, rubro-brunneo, basi viridi ; columella subsi- 



nuatd et labii refiexi margine nigricantibus ; aperturd alba. 



Long. 2§ ; lat. If poll. 



Var. a. Strigis angulatis albidis et nigricantibus concinne marmorata ; 



anfractu basali fasciis 2 subalbidis cincto. 

 Hab. ad montem Isarog insula? Luzon. 

 Legit H. Cuming in sylvis. 

 Var. b. Obscurior ; anfractu quinto albido superne unifasciato, an- 



fractu basali albido trifasciato. 

 Hab. ad Calanang insula? Luzon. 

 Legit H. Cuming in sylvis. 



This species, the most elegant of all the Bulini which I have yet 

 seen, is named in honour of His Royal Highness Prince Albert. 

 The form and rich but elegant colouring of the shell combine to make 

 it very beautiful. The pattern, as in the two last species, resides in 

 the epidermis, and, when the shell is plunged into water, disappears ; 

 but the green at the base remains unchanged, as in the last species. 

 Mr. Cuming found var. a. on the leaves of trees in the woods at 

 the foot of Mount Isarog, in the province of South Camarines, at 

 the south-east end of Luzon. It was very rare, for Mr. Cuming, 

 after a search of many days, could only procure six specimens. 



Var. b. was found in dense woods, also on the leaves of trees, in 

 the province of the Laguna, at Calanang, in that island. — W. J. B.

 The exhibition was resumed of the new species of Shells collected 

 by H. Cuming, Esq. in the Philippine Islands, and the following de- 

 scription of new species, by W. J. Broderip, Esq., was read. 



Helix (Carocolla) Regin^e. Car. testd hyalina, prasind, lineis 

 incrementi oblique striatd, lineolis transversis creberrime decussatd 

 suberectd, antice compressd ; anfractibus 3, ultimo latissimo, acuto, 

 suturam versus concinne ccdato ; aperturd infra angulatd ; labii 

 margine subexpanso, acuto.

Hab. ad Sibongam Insula? Zebu foliis arborum hserens, rarissima. 

 Legit H. Cuming in sylvis.
