476 Mr. R. Etheridge, Jun., on the Gasteropoda 



rounded below." There can, however, be no possible doubt 

 that these examples, including the figured specimen, had 

 tubercles on the lower side, as on the upper ; these can even 

 now be indistinctly traced by the naked eye, but are more 

 distinctly perceptible to the touch on passing the finger round 

 the edge of the large whorl. This fact was noticed by Mr. J. 

 de C. Sowerby, who, writing some few years later than Prof. 

 Phillips, says, in describing E. pugilis, " the tubercles be- 

 neath are sometimes very slightly prominent or irregular, when 



it approaches to E. bifrons, Phill and is probably a 



variety of it " *. Later on Mr. Sowerby united the two forms 

 under the name of E. pugilis, var. bifrons |. The shell 

 figured by Phillips also served Mr. J. de C. Sowerby as his 

 type ; he expressly states that his illustration was taken from 

 an example in the Gilbertson collection ; and an inspection of 

 the shells confirms this statement. I suspect this example 

 has met with an accident since it was figured by Messrs. 

 Phillips and Sowerby. It is in five pieces, no indication of 

 which is shown on Mr. Sowerby 's illustration ; had such frac- 

 tures existed they would have been shown, so very faithfully 

 were all the representations throughout the ' Mineral Con- 

 chology,' as a rule, executed. The union of E. bifrons with 

 E. pugilis was made by Prof, de Koninck, at much about the 

 same time \ as proposed by Mr. J. de C. Sowerby; and in 

 this they have been followed by Prof. M'Coy, who likewise 

 drew attention to the resemblance of E. tuberculatus, De Kon. 

 Notwithstanding the more elevated spire of this, I think it 

 very probably only a variety of E. bifrons or E. pugilis, 

 whichever name may be adopted. It is the

The Gilbertson collection contains two specimens of this 

 variety of the foregoing species ; neither of them, however, 

 is that figured by Mr. J. de C. Sowerby §, nor can I find any 

 specimen in the " Sowerby collection " corresponding with 

 the figures in question.
