2. LioTiA ECHiNACANTHA, Melvill & Stanclon. 

 Liotia echinacantha, Melvill & Standen : Ann. & Mag. Nat. Hist., 

 vol. xii (1903), p. 293, pi. xx, fig. 9. 



Hah. — Persian Gulf; Gulf of Oman, near Maskat, 10-15 fathoms. 



This verj' beautiful shell, which occurred in some numbers at the 

 above locality, is noticeable for its fluted spines, the nearest ally- 

 perhaps being L. Briareus, Dall, which I know only by the figure 

 and description,^ but that seems a species of even more ornate 

 character and sculpture. Both these species, echinacantha and Briarem, 

 may belong to the subgenus Arene, but the present new form, at all 

 events, possesses no scarlet radiating coloration on the whorls. 



3. LioTiA EOMALEA, Melvill & Standen. 

 Liotia romalea, Melvill & Standen: Ann. & Mag. Nat. Hist., vol. xii 

 (1903), p. 293, pi. XX, fig. 8. 



Hal. — Persian Gulf, Sheikh Shuaib Island, 10 fathoms; Maskat, 

 10-15 fathoms; also Gulf of Oman, lat. 23° 30' N., long. 57° 10' E., 

 10 fathoms, and lat. 24° 58' N., long. 56° 54' E., 156 fathoms, in 

 shell- sand. 



A typical Liotia, with obscurely five-angled and thickened peristome, 

 and cancellated whorls, the last whorl thrice spirally keeled. 



It remains only to say that Adeorbis, of which genus but two 

 exponents have yet been noted from these seas, is now by universal 

 consent removed from the proximity of the Cyclostrematidae to a place ! 

 amongst the Tsenioglossa, near the Skeneidae and Litiopidae.
