18. messorius, f. 20, Sowcrby. — Testa subviride fusca, 

 breviter claviformi, spiraliter lirata, longitudinaliter plicato- 

 bituberculata ; varicibus crassis, pone excavatis, ad angulurn 

 spina brevi curva, ad canalem spina producta arcuata, et 

 intra spina parva armatis ; apertura subrotunda, labio interno 

 plicato, labio externo intus dentato, extus crenulato ; canali 

 brevi. — The curved spine below the aperture on the canal is 

 shaped like a reaping hook. The canal is in most specimens 

 more gradually sloped than in the specimen figured. 



19. chrysostoma, f. 83, Gray. — Testa breviter clavata, 

 ventricosa, spiraliter lirata, inter varices nodoso-triplicata, 

 subaureo-fulva ; spira brevi, anfractibus angulatis, depressis ; 

 varicibus crassis, tuberculatis, ad angulum subspinosis ; aper- 

 tura magna, aurea, labio interno lato, medio crenulato, labio 

 externo denticulato, margine crenato, canali breviusculo,

 lum subspinosis ; apertura subovata, marginibus crenulatis, 

 canali breviusculo, oblique subrecurvo. — Differing from the

 named M. Cracherodi, in the British Museum, is probably 

 an immature specimen of this.

 pyramidata, inter varices spiraliter lirata, longitudinaliter tri- 

 tuberculata ; varicibus rotundis, dorso foveolatis ; spinis bre-
