larly-pointed projections. Cepbalon large and deep, produced in front to an 

 acute, deflexed rostrum, lateral parts, as it were, swollen, and forming a broad 

 lobe quite concealing the base of the inferior antennae. Coxal plates com- 

 paratively small and narrow; 3rd pair not expanded distally; 4th pairs less 

 deep than the former, and triangularly pointed below. Epimeral plates of 

 metasome very large. Eyes wholly absent. Antennae less slender than in 

 Syrrlioc, and nearly equal-sized in female. Anterior lip short and broad, 

 transversely truncated at the tip; posterior lip with the lateral lobes insi- 

 nuated near the tip. Mandibles extremely stout and compact, cutting part 

 conically produced, and not at all dentated, molar expansion replaced by a 

 very broad transverse triturating surface, palp extremely minute and slender, 

 though composed of the 3 usual joints. Maxillae nearly as in Si/rrhoe. Maxil- 

 lipeds with the masticatory lobes very broad, and armed with a row of extra- 

 ordinarily strong spines, palp slender, with the 3rd joint linear, dactylus 

 small. Gnathopoda nearly exactly alike, both in size and structure, both 

 pairs very feeble, with the propodos extremely small, and imperfectly sub- 

 cheliform, the palm being very oblique and wanting the strong denticulated 

 spine present in Sijrrlior. The 2 anterior pairs of pereiopoda extremely 

 slender and feeble; the 3 posterior pairs much stronger and successively 

 increasing in length, basal joint rather expanded. Uropoda nearly as in 

 Syrrlioe. Telson deeply cleft. 



Remarks. The present new genus is founded upon the form described 

 by the author, at an earlier date, as Bruzelia serrata. On a closer compa- 

 rison of the several genera of this family, I have however found that the 

 above-named form, though in its outer appearance somewhat resembling the 

 species of the genus Bruzelia, yet differs in some points very markedly, 

 and ought therefore more properly to be regarded as the type of a separate 

 genus, somewhat intermediate in character between the genera Syrrlioe and 

 Bruzelia. From the latter genus it is especially very prominently distin- 

 guished by the structure of the telson, which is not entire as in that genus, 

 but deeply cleft as in Syrrlioe. In the structure of the gnathopoda and partly 

 also in that of the oral parts it somewhat differs from both these genera. 

 The genus comprises as yet but a single species, to be described in the sequel.
