14 MUREX. 



tialibus, superiori bifurcato ; ad caudam tribus recurvis ; 

 cauda elongata, distincta, angusta, labio externo acutissime 

 dentato. — Lighter, more slender, with the whorls of the spire 

 more distinct and produced than M. palma-rosce, and having 

 small interstitial fronds between the larger ones. 



60. affinis, f. 45, 46, Reeve. — Testa quam M. Saulice 

 brevior crassior, frondibus brevibus, intermediis nullis. — 

 The shells which we would place in this species differ from 

 M. Saulke in having no intermediate fronds, and from M. 

 Palma-rosce in having very short ones not at all branched 

 or spread at the ends. The white fronded variety was 

 figured in the Conch. 111. as a variety of M. maurus. 



61. Sterle, f. 38, Reeve. — Testa trivaricosa, breviter 

 fusiformis, crassa, spiraliter scabroso-costata, inter varices 

 unituberculata ; fusca, nigrofasciata ; varicibus crassis, 

 frondosis ; frondibus purpureis foliatim spinosis ultimoe 

 varicis superne et medio quaternis superiori producto, 

 bifurcato ; interstitialibus parvis ; ad canalem duabus ; cauda 

 brevi. — A shell of thick and short growth, having the small 

 intermediate fronds of M. Saulke and the prominent bifur- 

 cated upper frond of M. palma-rosce. 



62. spectrum, f. 51, Reeve. — Testa elongato-fusiformis, 

 curvantia-fuscescens, subgranosa, spiraliter tuberculatim 

 lirata, inter varices triplicatim tuberculata, liris tuberculatis 

 castaneo pictis ; varicibus crassis, frondosis ; frondibus con- 

 spicuis, muriato-foliatis, crispatis superioribus longe extanti- 

 bus, subramosis, alteris brevioribus, tribus parvis intermediis ; 

 canali elongato, rectiusculo. — Quite distinct from Murex 

 palma-rosce in all details of sculpture and colour, yet 

 resembling it in general form. I cannot doubt its identity 

 with Chicoreus imbrieatus of Higgins and Marrat, described 

 from specimens collected in the Island of Grenada. 



63. rubiginosus, f. 61, Reeve. — Testa trivaricosa, scabra, 

 fulva, fusco-nigrescenti tseniata, subventricosa subangulatim 

 fusiformis ; spiraliter lirata, inter costas prominente uni- 

 tuberculata ; varicibus crassis ; frondis subramosis, latiusculis, 

 subpalmatis apertura alba magna ; spira et cauda sub- 

 sequalibus. — If an ordinary specimen of M. aclustus were 

 very much enlarged, spread, and lightened in colour, and its 

 fronds a little flattened, it would present a resemblance to 

 this species. At first it was thought that M. rubiginosus 

 might be M. iorref actus with more fully developed fronds,
