MUREX. 21 



infra medium longe interruptis, turn ad canalem breviter 

 productis, ad inargineru dentatis ; apertiira parva ; canali 

 clauso. — The shell we have figured is unusually short. The 

 interruption in the varical fringe between the body of the 

 whorl and the canal is remarkable. 



92. osseus, f. 91, Reeve. — Testa oblongo-fusiformis albida, 

 medio anfractuum fascia fusca cincta, M. Gambiensi similis, 

 major, spira longe pyramidata ; ala ad canalem parva ; canali 

 peculiariter iuflato. — A larger shell than either of the two 

 preceding with more produced pyramidal spire, and curiously 

 inflated covering to the broad caudal canal. 



93. gambiensis, f. 94, Reeve. — Testa pallide fulva, bine 

 illic rubro maculata, M. pinnigeri similis, multo magis 

 elongata, alis baud tantum productis. — Formed on the same 

 model as the preceding, but much more slender, with nar- 

 rower wing-fringes, less produced hook-like projections above, 

 and with some distinct scattered reddish spots. 



94. alabaster, f. 124, Reeve. — Testa angulatirn fusiformis 

 ventricosa, albida, spiraliter obscure costata, inter varices 

 bituberculata ; varicibus crassiusculis late membrano- 

 fimbriatis superne" lobo tubiformi crasso valde producto, 

 canaliculato armatis ; canali breviusculo, fere aperto, apertuxa 

 magna ; spira producta pyramidata, anfractibus angulatis. — 

 The original specimen, which was found beach-rolled on the 

 shore of one of the Philippine Islands, is unlike any other. 



95. acanthofterus, f. 90, 127, Lamarck. — Testa fusiformis, 

 alba, interdum supra angulum anfractuum fusco fasciata, 

 spiraliter eostis plus minusve distinctis cincta, inter costas 

 minute cancellatis, vel fere laevis, varicibus continuis, alatis, 

 late fimbriatis ad angulum anfractuum in lacertum canali- 

 ferum utrinque laciniatum projectis, lacinia infra lacertum 

 contracta, turn ad aperturam rotundatim expansa, infra ad 

 canalem coarctata et expansa, apertura subovata, margine 

 externo denticulato : spira pyramidata, anfractibus angulatis. 

 — The projecting chanelled arm at the angle of each whorl 

 forms a series of fringed hooks on the spire. 



96. teiformis, f. 92, Reeve. — Testa intense fusca vel 

 pallide griseofulva, rugosa, M. acanthopteri similis, sed alis 

 ad angulum anfractuum baud tantum projectis et infra con- 

 tracts, anfractibus inter varices bilobatis vix angulatis. — Mr. 

 Reeve was right in distinguishing this species from M.
