44 DR. G. S. BRADT ON THE 



blunt apices ; external margins of all the joints ciliated. Lamina? of the fifth pair of 

 feet (fig. 5) broad, subovate, nearly equal in length ; margins of the external lamina 

 finely ciliated, and bearing six subequal apical setae ; inner lamina with five setae on 

 its subtruncate apical margin. Abdominal segments slightly overlapping each other, 

 but altogether devoid of seta? or serrulations Male unknown. 

 Hab. Otago Harbour, between tide-marks. One specimen only. 



Genus Haepacticus Milne-Edwards. 



1. Harpacticus glaber, sp. nov. (Plate XII. figs. 6-11.) 



Female. — In general appearance like H. chelifer. Antermules (fig. 6) slender, 

 moderately setiferous, eight-jointed ; lengths of the joints as in the following formula :

io'i"i n ' 8 ' 4 ' 4 ' s ' v Antennae (fig. 7) stout, nearly as long as the antennules, bearing 

 a small two-jointed branch, extremity of the last joint abruptly truncated and bearing 

 two long, rigid, finely pectinated spines and four slender geniculated seta? ; posterior 

 foot-jaw (fig. 8) almost exactly similar to that of H. chelifer. Outer branch of the 

 first pair of feet elongated, two-jointed, terminating in three subequal, blunt, slightly 

 curved and very finely pectinated claws ; outer margins very sparingly ciliated ; each 

 joint bearing within a short distance of its distal end a single short marginal seta: 

 inner branch terminating in a strong slightly curved claw ; the long first joint slightly 

 ciliated and having near its apex a slender seta. Feet of the fifth pair two-jointed 

 (fig. 10), basal joint wide, its inner portion distally produced and giving attachment 

 to three long seta? ; terminal joint much narrower, margins ciliated, with three long 

 seta? at the apex and one on the outer edge. The spines of the swimming-feet, like 

 those of the first pair and of the antenna?, are minutely pectinated. The margins of 

 the abdominal segments (fig. 11) are smooth except for a few minute hairs at the 

 lateral angles and on the caudal lamina? ; principal tail-seta? very long. 



Hab. Otago Harbour. One specimen taken in the surface-net. 



From H. chelifer this species may be distinguished by the number and comparative 

 lengths of the joints of the antennules, by the armature of the antenna?, the non- 

 spinous margins of the first pair of feet, the different build of the fifth pair, and the 

 almost smooth margins of the abdominal somites. There seem to be points of 

 difference also in the mandibles and maxilla?, but these I have not clearly made out. 



Genus Peltidium Philippi. 



1. Peltidium nov^e-zealandi^:, sp. nov. (Plate IX. figs. 28, 29 ; Plate XII. 

 figs. 12-15.) 



This is in general build and appearance exactly like the common European species 

 P. interruption, Goodsir, the only important differences being found in the posterior
