276 REV. R. B. "WATSON ON THE 



it may be permissible to retain an old friend, whom if we 

 forsake to whom shall we turn. Omalaxis of Deshayes is 

 like one of Adanson's facetious names. Homalaloxis of 

 Herrmansen is fatuous. Homalaxis is a hybrid, neither 

 Greek nor Latin. Torinia is a mere guess, and thereafter 

 the mazes of Ilaira, JEuomphalus, Evompthalus, Omalaxon, 

 Pseud omalaxis, &c. may well send us back thankfully to 

 Bifrontia, where if we are ignorant we are at least humble. 

 Monterosato (Conch, d. profundita &c. Palermo, p. 16), 

 who adopts the last of the above-quoted generic names, 

 rejects the identification of this Madeiran species with that 

 of Philippi. His opinion deserves the utmost respect, but I 

 am not able to adopt it in this case. 



35. Bittium depauperatum, 1897, Watson, antea, p. 245. 



36. Bittium incile, 1897, Watson, antea, p. 246. 



37. Bittium reticulatum, 1778, da Costa (as Strombiformis), Brit. 



Conch, p. 117, viii. 13 : Gwyn Jeffreys, Brit. Conch, iv. 258, 

 iv. 4 ; & v. 217, lxxx. 4. Hob. Prom the Lofotens (Loven) to 

 Mediterranean and Canaries. (M., L., N., Jn., W.) Every- 

 where ; very common. 



38. Bulla (Haminea) hydatis, 1767, Linne, Syst. Nat. p. 1183 : 



Gwyn Jeffreys, iv. 437, viii. 5 ; & v. 224, xcv. 3. Hab. Gt. 

 Britain to Mediterranean, Canaries, and St. Helena. (W.) 

 Not common and small. 



39. Bulla punctata, 1868, A. Adams, Cuming's Collection, teste 



Sowerby in Beeve's Conch. Icon, xvi., Bulla sp. 15. Not 

 Bulla punctulata (so in Explanation of Plates and Index, 

 pp. 604 & 607, corrected from B. punctata of the text) of 

 Sowerby's Thesaurus ; not Bullcea punctata of John Adams, 

 Trans. Linn. Soc. v. 1, pi. i. figs. 1, 2, where there is a Philine, 

 and which in Sowerby's Thesaurus, n. 600, cxxv. 161, is 

 given by A. Adams as B. punctata ; nor is it the Bulla 

 punctata or punctulata of C. B. Adams, which (teste 

 Carpenter) is the B, Adamsi, Mke. ; nor the Atys (Roxania) 

 punctulata of A. Adams. Whether Pilsbry's Manual of 

 Conch, contains the species is, I think, very doubtful ; the 

 figure pi. xxvii. 40, 41, taken from Reeve, not good in the 

 original, is not mended in the copy. — Hab. Madeira and 

 Canaries (f. McAudrew, who gives it as Bulla ampulla). 

 (L., Jn.,W.) Everywhere; pretty frequent, especially young 

 shells.
