in front to a comjiressed linguiform lobe, posterioi' lip rather large, mem 

 branons. Mandibles very powerful, flatting edge provided at the inner eorjier 

 with one or two secondary teeth, molar expansion rather prominent, with the 

 tip conically produced and densely ciliated; palp shorter than the mandible 

 and originating much nearer its extremity than does the latter. First pair of 

 maxillae with the masticatory lobe rather large, obliquely truncated and armed 

 with strong denticulated spines; basal lobe small, bisetose; palp large, spathu- 

 late, and armed on the terminal edge with short aculei. Second pair of max- 

 illae with the inner lobe much smaller than the outer. Maxillipeds large, 

 nuisticatory lobe broadly oval, not reaching to the end of the antepenultimate 

 joint of the palp ; the latter robust, with the tenninal joint claw-.shaped. An- 

 terior gnathopoda short and stout, distinctly subcheliform, the ])ropodos being 

 nearly transversely truncated at the tip, dactylus short and simple. Posteritu- 

 gnathopoda moderately slender, propodos oval, slightly })roduced at the tip be- 

 neath the minute dactylus. Perei(ii)oda rather elongate, basal joint of the '6 

 posterior pairs successively increasing in size. Branchial lamellae large and 

 distinctly plicated transversally on both sides. Last pair of uropoda consi- 

 derabl\' projecting beyond the jjreceding pair, rami lanceolate, denticulated 

 and setous on the edges. Telson of moderate size, deeply cleft. 



Remarlis. — In the restricted sense in which the genus is here taken, 

 it only comjirises one of the Kroyerian species, viz., his Anoni/.r lagcna. An- 

 other nearly related species discovered by Boeck, A. LiVjeborgii, will be de- 

 scribed together with the type species in the seqiiel. Besides, 3 other forms 

 may without any doubt be adduced to the same genus, viz., A. ampulloides 

 S]). Bate, A. Zschauii PfefFer, and Lijt<ianai<sa Martensi (ioes. Proljably also 

 several other exotic forms may on closer examination be found to l)elong to 

 the present genus.
