PROF. E. VON MARTENS ON THE SHELLS 



1ST.B. — Cyclophorus speciosus, Philippi, Zeitschr. f, Malacozoo- 

 logie, 1847, p. 123 (Cyclostoma), figured by Pfeiffer & Kiister, 

 Cyclost. pi. 25. figs. 1-3 ; Pfeiffer, Mon. Pneum. i. p. 56, locality 

 unknown, appears to be a species distinct from all these forms, 

 and perhaps the same as that figured in the ' Conchologia 

 Indica,' pi. 33. fig. 4, under the name of aurantiacus ; the figure 

 called C. speciosus in this last work, pi. 104. figs. 4 & 7, is again 

 different. The true C. malayanus, Bens., from Penang Island, 

 is, according to the figure given by P. Stoliczka in Journ. As. 

 Soc. Bengal, vol. xli. pt. 2, pi. 10. fig. 5, remarkably more conical 

 and elevated than any of the varieties of aurantiacus here 

 described. 



2. Cyclophortjs ophis, Benson ; Tlieob. Sf Hani. Conchol. Ind. 

 pi. 144. fig. 6. 



Allied to C. aqidla, Sow., but the peristome very broad. 

 Elphin stone Island. 



3. Cyclophortjs expanstjs, Pfeiffer, Proc. Zool. Soc. 1851, 

 p. 242 ; Mon. Pneum. i. p. 65 ; Pfeiffer Sf Kiister, Cyclostoma, 

 pi. 39. figs. 20, 21 ; Peeve, Conch. Icon. xiii. pi. v. fig. 18 j Conchol. 

 Indica, pi. 2. figs. 3, 4. (PI. XV. figs. 7, 8.) 



Mergui. (Seems confined to the Tenasseritn coast.) 



In the specimens collected by Dr. Anderson the expansion of 

 the peristome is still broader than in the figures given by Reeve 

 and the Conchol. Ind. 



4. Cyclophortjs zebrintjs, Benson. 



(a) typicus : acute angulatus, peristomate albo. — Benson, Asiat. 

 Journ. v. 1836. p. 355 ; Pfeiffer Sf Kiister, Cyclost. pi. 34. 

 figs. 21-23 ; Mon. Pneum. i. p. 71 ; Conchol. Ind. pi. 2. fig. 2 ; 

 Nevill, Hand-list, i. p. 268. 

 King Island. I cannot distinguish the specimens collected 

 on that island from the normal zebrinus, which is stated to live 

 on the Khasi hills. Khasi hills, Bhamo (Anderson). 



(J>) aureolabris. — Nevill, Hand-list Moll. Ind. Mus. i. p. 268. 

 Peristome intensely yellow. 

 Mergui. Silsagor (Peale). 



(c) amhiyuus : minor, obtuse angulatus, costulis spiralibus 

 obKolcHccntibiiH, fulvuH, infra suturarn maculis fuscis et albidis 

 ornatus, nubtus fasciolatus, umbilico sat angusto, peristo- 

 mate albido. DiaiDi maj. 28, alt. 2L; apart, diam. et alt. 

 15 millim. (PI. XV. fig. <).)
