13. Cyclotus suluanus. (PI. IV. fig. 7.) 

 Cyclotui suluanus, Mollendorff, MSS. 



Testa globosa, anguste umbilicata, pallida, rufo-fusco copiose macn- 

 lata et fulgurata, apicem versus nigrescens, infra peripheriam 

 albidam zona colorata distincta ornata, infeme circa umbilicum 

 pallida, baiid maculata : anfractus 5, perconvexi, lineis incrementi 

 obliquis teniiibiis aliisquc spiralibus subobsoletis striati, ultimus 

 anticc levissime desccndens ; apertura circularis, longit. totius | 

 paulo supcrans ; peristoma leviter incrassatum, vix cxpansum ; 

 operculum i;trinque leviter eoncavum, anfractibus circiter 7 ad 

 suturam carinatis, transversim oblique striatis. 



Diam. maj. 21 miUim., min. 17, alt. 18; apertura 10 longa et lata. 



Hah. Sulu {Dr. Hung erf or d* s collection). 



Two specimens of this species in the British Museum 

 originally formed part of Dr. Hungerford's collection, and 

 they are refen-ed to by the Rev. A. H. Cooke (P. Z. S. 1892, 

 p. 461) under the above name. The label accompanying 

 them, in Dr. !Mollendoi-ff's handwriting, gives the locality 

 " Sulu," so that I think we may safely conclude that the 

 specimens are from that island. 



The species is remarkable for its globose form and its 

 cyclophoroid appearance, considerably recalling the aspect of 

 C. exaltatus, Pfr., from Hong Kong. The operculum fits 

 within the extreme margin of the aperture, so that its outer 

 surface is almost flush with the peristome. 



14. Cyclotus variegatuSy Swainson, var. 



Cyclotus variegatus, Sw., Eeeve, Conch. Icon. figs. 29fl, A; Kobelt, in 

 Samper's Reisen im Arch. Philippinen, Landdeckelschuecken, p. 5, 

 pi. i. fig. 5. 



Hah. Sulu {Hungerford collection in Brit. Mus.) ; Bongao 

 {Everett^. 



A fine single example of this species was obtained from 

 Dr. Hungerford's collection with a label in Dr. O. F. v. 

 Mollcndorff's liandwriting as follows : — '^Cyclotus rariegaiiis, 

 Swains., yawgrandis, Mlldft'. Sulu. (Running into ^>a^c/<«*a7z- 

 ensis, perhaps new !)" 



I certainly agree with Dr. Mcillendoi-fi' in his determination, 

 and the example obtained by Mr. Everett at Bongao, 

 although somewhat smaller ;than the shell in question, evi- 

 dently belongs to the same species. C. BoxaJli of Godwin- 

 Austen and G. euzomts, Dolirn, arc extremely close allies, 

 the latter, however, being distinguishable by its distinctive 

 coloration.
