'.». semipicta (f. 12, 13), Sowb. — T. brevi, ventricosa, medio 

 anfractuum et infra bifasciatim maculis rubris rotundis oblique 

 dispositis picta, spira brevi, acuta, sutura profunde canaliculate, 

 varice canalifero, parvo, umbilico angusto, epidermide pallide lutea. 

 — More rounded than E. canaliculaia, with rounded spots ar- 

 ranged in a broad band in the centre of the whorls, about four 

 spots deep, and in a lower band two spots deep; the canaliferous 

 varix and the umbilicus are narrow. 



10. curysostoma (f. 15, 16 ; E. canaliculata, var., pi. 215, 

 f. 3), Sowb. — T. ventricosa, quaui E. canaliculata magis ovali, 

 canali suturse magis angusto, anfractibus superne versus spiram 

 appressis, maculis faseiatim nebulosis, apcrtura aurantia seu rosea. 

 — The true E. canaliculata has a rhomboidal or squarish form, 

 which is not found in three shells which we have figured. The 

 mouth in that species is bluish-white, while in the several varieties 

 of E. e/tn/sostoma there is a tendency to colour, and some speci- 

 mens are bright orange. The spots also are smaller and more 

 mottled and blended. The sutural canal is invariably narrower. 

 \ ar. f. 10 is almost as rounded and short as E. Molliana (Valen- 

 liana, Auct.) but is distinguished without difficulty. 



11. Boknuensis (f. 14), Sowb. — T. ovali, acuta, tenuiuscula, 

 maculis magnis, superioribus subangulatis, alteris rotundis, an- 

 fractibus superne appressis, canali suturali angusto, callo spirali 

 umbilici crenulato, angusto, canali parvo, labro infra subcontracted 

 — More oval in form, more dark in the colour of its more rounded 

 spots, with narrower sutural canal, smaller siphon al canal, and 

 outer lip more contracted at the base than E. canaliculata. 



12. EormosvE (f. 17, IS), Sowb. — T. ovali, acuta, maculis 

 magnis rubescentibus uudulatis picta, anfractibus subiuflatis ad 

 suturam angulation depressis, umbilico latiusculo, umbilici callo 

 spirali castaneo, anfractu ultimo infra canaliculate — The form 

 and suture of this shell resemble those of E. Japonica, but thi 

 markings arc totally different.
