outer ramus about as long as the basal one. Telson scarcely as long as it 

 is broad at the base, ti]) obtusely pointed, entire. Colour yellowish mottled 

 with dark brownish and reddish pigmentary spots, forming more or less 

 distinct, transversal bands. Length of adult female scarcely exceeding 5 mm. 



RemarJcs. — As above stated, this form was referred by Boeck to 

 the genus Anclania, though it differs materially in some characteristics from 

 the diagnosis of the genus given by that author, for which reason I have 

 here regarded it as the tj'pe of a separate genus. It is easily recognized 

 from the other northern Stegocephalidaj especially by the structure of the 

 last pair of pereiopoda. 



Occurrence. — The species is b}^ no means infrequent off the west coast 

 of Norway, in moderate depths, from 20 to 100 fathoms, occurring, in some 

 places, even in great abundance. It extends northwards along the Nordland 

 coast, at least to Lofoten. Out of Norway, it has not yet been recorded. 



Gen. 6. Andaniella, G-. 0. Sars, n. 



Body short and compact, with rather firm integuments. Cephalon 

 comparatively small, wi'rhout any distinct rostral projection. Coxal plates 

 rather large and deep, 4th pair very bi'oad, and quite encompassing the 

 succeeding pair interiorly. Eyes wholly wanting. Superior antennae about 

 as in Andanioims : inferior ones much shorter and stouter. Epistome produced 

 in front to an accuminate lappet. Anterior lip rather large, and distinctly 

 bilobed; posterior lip with the lateral lobes rather narrow, and blunted at 

 the tip. Mandibles strong, with the cutting edge coarsely dentate, as in 

 the genus Stegorephalus:. First pair of maxillae with the basal lobe compara- 

 tively small, masticatory lobe, on the other hand, very large, and armed 

 with strong denticulated spines, palp very small, uniarticulate. Second pair 

 of maxillae nearly as in the preceding genus, but with the outer lobe com- 

 paratively larger, and having only 4 rather coarse apical spines. Maxiliipeds 

 with the basal lobe very short, masticatory lobe, on the other hand, largely 

 developed, reaching far beyond the antepenultimate joint of the palp, the 

 latter extremely slender, and nearly naked. G-nathopoda comparatively 

 more powerful than in the other Stegocephalidse, anterior ones somewhat 

 shorter than the posterior, dactylus in both pairs very strong and curved, 

 armed with coarse spines. Peniiltimate pair of pereiopoda with tlie basal 

 joint linear, not at all expanded. Last pair of pereiopoda much shorter than
