" Beck originally proposed the name JSubulina for the following 

 species : — (i) A', cyanostoma Eiipp., (2) tuvritellata Desh., (3) stria- 

 tella Kang, (4) malaguetana Eang, (5) monoceros Beck, {Q) propinqua 

 Beck, (7) terebrasfer Lam., (8) octona Ch., (9) crotalariae Schum., 

 (10) carinulata Beck, (11) jmpaefonnis Beck, (12) S. ? sericata Beck, 

 The first species of the list was made type of Homorus by Albers, 

 1850; species 6, 10, 11, 12, are nude names; 7 is an Obeliscus; 

 2 and 4 are species of uncertain generic relationships ; leaving 

 species 3, 5, 8, 9 to represent the group of S. octona. Gray in 

 1847 and Herrmannsen, 1849, agreed in selecting as type of 

 Subulina the commonest and best known species, S. octona — a 

 course approved by practii-ally all later writers who have 

 recognized tlie group."' {Pihbr;/.)
