Iredai.e. — Suter's "Manual of the New Zealand Mollusca." 465 



I have since observed that Penion Fischer is invalid, as Philippi had 

 previously used it. and therefore introduced (Proc. Mai. Soc. (Lond.), vol. xi, 

 p. 175, 1914) Verconella, with Fusus dilatatus Quoy and Gaimard as type. 

 Austrofusus Kobelt cannot be used, as the type of that section is quite 

 another style of shell. It looks similar to " S" mandarina (Duclos), but 

 examination of the shells shows them to differ considerably, and the re- 

 semblance to be similar. I cannot, however, separate " S." mandarina 

 Duclos subgenerically from S. dilatata (Q. & G.) : they agree in every 

 essential detail to me. Martyn's Buccinum nodosum is, however, a very 

 different type of shell, and it may later prove generically distinct ; in the 

 meanwhile I propose the subgenus-name Aethocola for it alone. 



My reading of the genus would be, — 



Genus Verconella Iredale, 1014. Verconella Ixedale, Proc. Mai. Soc. 



(Lond.), vol. xi, p. 175, 1914. Type : Fusus dilatatus Quoy and 



Gaimard. Synonym : Penion Fischer. Man. de Conch., p. 625, 1884 



(not Penium Phillippi, Verh. z. 1. Ges. Wien. vol. xv, p. 741, 1865). 

 Subgenus Verconella s. str. 



Verconella dilatata (Quoy and Gaimard, 1833). 



maxima (Tryon, 1881). 



mandarina (Duclos, 1831). 



ruled icta (Watson, 1886). 



caudata (Quoy and Gaimard, 1833). 



Subgenus Aethocola nov. 



Verconella nodosa ( Marty n, 1784). 



Cominella eburnea (Reeve). [P. 383.] 



This name, according to Suter's synonymy, must displace Cominella 

 costata (Quoy and Gaimard). as the basis of that name is Buccinum costatum, 

 which is invalidated bv the prior usage of Linne (Svst. Nat., ed. x, p. 738, 

 1758). 



Cominella qaoyana (A. Adams, 1855). [P. 384.] 



Kobelt proposed Cominella huttoni for the species so named, as there 

 was a Buccinum quoyi Kiener which comes into the same genus, Cominella. 

 It has been continually used, but, according to the nomenclatural laws 

 now adhered to, A. Adams's name must be reverted to. 



Cominella adspersa (Bruguiere, 1789). [P. 385.] 



Martyn's Buccinum maculatum is invalidated by Linne's prior use (Syst. 

 Nat., ed. x, 1758, p. 741). Bruguiere's name comes next, and claims usage. 



Fam. Fusidae Iredale. [P. 392.] 



I propose this name to replace Dall's family Colubrariidae, basing the 

 name upon the oldest genus-name in the family. The following account- 

 will clearly show the. extreme difficulty and amount of time necessary if 

 one attempts to name a shell correctly both generically and specifically. 



When I was investigating the relationships of my genus Jeannea (Proc. 

 Mai. Soc. (Lond.), vol. x, p. 220, 1912) it was necessary to fix the genus 

 Pisania. The only member T was familiar with was Pisania reticulata 

 A. Adams, and mj Jeannea was nothing like that. Under the genus Pisania 

 in the British Museum collection rather an incongruous association of shells 

 appeared, amongst them being Pisania reticulata. The type of Pisania
