Amphipodous Crustacea of New Zealand. 331 



2. Aora typica } Kroyer. 



Of this species I got one specimen in the dredge, along with 

 the preceding. This agreed well with the characters given in 

 Brit.-Mus. Cat. p. 161, differing only slightly in the following 

 respects : — The superior antennae were about as long as the 

 animal ; the propodos of the first gnathopoda, as well as the 

 last four joints of the second gnathopoda, were very hairy ; 

 telson quite smooth. 



Colour yellowish, with small black spots chiefly on the 

 lower parts of the body and on the limbs. Length '3 inch. 



The species has evidently a wide range, having been origi- 

 nally described from specimens obtained at Valparaiso. 



3. Microdeutopus maculatus, sp. nov. (PL XVI. figs. 5-8.) 



Animal smooth, slender. Coxas rather small. Superior 

 antennas considerably longer than inferior, two thirds as long- 

 as body; second joint of peduncle long and slender; third 

 short and furnished with a 5-6-jointed appendage ; flagellum 

 very slender, many-jointed, sparingly ciliated. Inferior an- 

 tennas strong, subpediform, with a stout olfactory denticle, and 

 furnished with numerous cilia ; third joint of peduncle short, 

 fourth and fifth very long ; flagellum short, indistinctly 6-7- 

 jointed. Mandibular appendage 2-jointed. Maxillipeds with 

 strongly-toothed appendages. Gnathopoda moderate, covered 

 with strong cilia : first pair rather the largest ; carpus rounded 

 on its inferior margin ; propodos oblong, with a very oblique, 

 curved palm defined by a strong spine ; dactylos strong and 

 curved, finely toothed on the inner margin : second pair 

 similar, but with the palm transverse and without the defi- 

 ning spine. Third pereiopoda shorter than preceding ; posterior 

 pair very long. Antepenultimate pleopoda reaching to ex- 

 tremity of ultimate pair ; base of the rami with a stout spine. 

 Telson with a broad apical notch, each side with a slender 

 spinule. Length *35 inch. 



Hob. A single specimen dredged in Dunedin Harbour in 

 4-5 fathoms. 



Apparently a very distinct species. 



4. Cyrtophium cristatum, sp. nov. (PL XVI. figs. 9-15.) 



Male. Eyes prominent. Pereion wider than deep, trans- 

 versely ribbed and tuberculate. Last segment of pereion and 

 three anterior segments of pleon elevated into prominent crests. 

 Antennas with long cilia on their inferior margins : superior 

 pair shorter than inferior ; peduncle reaching the extremity of 

 penultimate joint of peduncle of inferior, bearing a one-jointed
