I owe the identificatiori <>|" this specimen to Mr. Smith, who pronounces ii to 1"- a verj 



fine example of cagayanensis \ it is much larger than Reeve's specimen, being 25 Mill. in lenght, 



inr though Reeve's figure has the same length, it is according to text i ] /. 2 times magnified, 



over it is more elongated, the tubercles of the upper part of ribs are less conspicuous, the 



colour is yellowish-white, with tracés of red-brown spots near the aperture, especially one rather 



blotch below the suture, at some distance from tlie sinus. This species belongs to the 



section Brachytoma, often written Brachystoma, the first orthography being employed \>y Tryon 



on page 155. the second on page 17') of his Manual; Boettger (Nachrichtsbl. d. I). Mal. 



llsch. 1895, p. <> says Brachystoma, Cossmaxn (Lssai de l'aléoconchologie, part II, pag. 62) 



hytotna non Brachystoma. A worse evil is that the limits of the sections are so ill-defined, 



that no two authors agree in referring the species to one section or to another, under such 



circumstances I thought it letter not to quote them at all.
