698 MUREX. 



the base is umbilicated, the throat white, and the outer lip 

 double, toothed on the margin, and grooved on the inside ; 

 the colour is browni.sh or reddi.sh white, sometimes marked 

 with distant undulated darker lines. In the Variety, the spire 

 appears as if it had been pulled out while the whirls were 

 soft, in the same manner as often so remarkably occurs in 

 Bnccinum spiratum. 



LOTORIUM. 33. Shell angitlated, with decussated 

 varices, and longitudinally tuberculated ; 

 beak liexuous, and the aperture toothed.

 All Conchologists appear to have entertained doubts respect- 

 ing the Linnyean M. O/eariuin, M. Lotorium, and M. Pi- 

 leare, and the references given for these species in the Sys- 

 tema Naturae are so confused, that it may be doubted whe- 

 ther it will ever be possible satisfactorily to ascertain them. 

 Martini, in vol. iv. p. 89, has referred to his figures 1242, 

 1243, 1246, 1247, 1248 and 1249, for one species, and of 

 these the two former have been considered by Schroeter to 

 belong to M. Olearium, and the others to M. Lotorium. 

 In the Museum Leskianum, fig. 1246 and 1246 are quoted 

 for M. Lotorium, and 1247 and 1248 for M.Pileare, and 

 Bom's opinion is adopted, that M. Argus is the Linnaean 

 M' Olearium. Schroeter's references m the Einleitung to 

 his own figures are obviously erroneous, and in his work on 

 the Structure of Shells, he has considerably varied the syno- 

 nyms. Of Martini's figures which I have above quoted, 

 two are about two inches long and half as broad, and the 

 others are almost twice as large ; they differ from those of 

 M.. Olearium in having the transverse ribs much broader. 



PILEARE. 34. Shell with decussated varices, and 

 somewhat nodulous wrinkles ; aperture tooth- 

 ed, and the beak slightly bent upwards.
