24 MUREX. 



pallide carnea, spiraliter striata, inter varices unituberculata; 

 varicibus latissime superne et usque ad canalem expansis, 

 superne angulatis; canali brevissimo. — A winged species dif- 

 fering from M. Eurypteron in tbe wings not being so much 

 lobed, and being continued nearly to tbe end of tbe canal. 



106. phyllopterus, f. 107, Lamarck. — Testa trapezoidea 

 alba, interdum fusco late fasciata, obtusissime spiraliter 

 costata, inter varices prope medium unituberculata; vari- 

 cibus tribus latissime expansis lobatis superne perelevatis; 

 versus terminum canali extensis, canali subelongato; spira 

 acuminata, anfractibus angulatis; apertura ovata, margine 

 laqueato. — This species is much larger, much more angular 

 and alate and less ribbed than M. foliatus, to which it bears 

 a general resemblance. The original is described by La- 

 marck as white and somewhat ribbed. Miss Saul's banded 

 specimen may perhaps be correctly referred as above, 

 although it is doubtful. It is not without hesitation that I 

 withdraw the proposed name of trialatus. A smaller 

 specimen is found in the collection of the late Mr. Taylor, 

 which has a laterally laminated operculum. 



107. foliatus, f. 110, Lamarck.- — Testa oblonga trivari- 

 cosa, transverse distanter costata, alba, fusco late fasciata; 

 costis late fere ad canalis terminum alatis, alis lobatis, 

 superne elevatis, canali clauso apertura magna, ovata, antice 

 unidentato. — An oval, ribbed shell having the three varices 

 expanded broadly. The older writers above quoted were 

 perhaps more correct in placing this among the purpuras on 

 account of the lateral operculum, than later conchologists 

 have been in regarding it as a Murex. It is, however, an 

 extremely muriciform shell. 



108. Burnetii, f. 97, 128, Adam & Reeve. — Testa subo- 

 vata, fumoso-fusca, inter varices obtuse costata, medio tuber- 

 culata ; varicibus tribus late alatis, promineute lobatis profun- 

 dissime canaliculatis ad canalem dimidiatim terminantibus 

 canali oblique uncinato; apertura magna, ovata, labio 

 externo lobato, antice dente maximo armato. — The recent 

 importation of this curious species, with its deeply furbel- 

 lowed varices and its sublateral operculum, so different from 

 the worn specimen first figured, has disposed me to give the 

 second figure. 



109. macropteroiN, f. Ill, Deahayes. — Testa corneo-fusca,
