All the joints are somewhat setose, and the fourth bears a long curved 

 seta (the olfactory appendage ?). In the male there is usually a distinct 

 geniculation at the fourth and fifth joints, which are more or less swollen 

 and coalescent. The posterior antennae are furnished with 5 geniculated 

 setae at the extremity, and 2 on the inner margin of the terminal joint ; 

 the 4-jointed secondary branch is also furnished with a few setae. Both 

 pairs of foot-jaws slender, second pair the strongest. First pair of feet 

 with the inner branch consisting of two long joints, the first of which is 

 dilated above the middle and bears a plumose seta near its extremity, the 

 second is straight, bears a plumose seta on its inner margin, is pectinately 

 ciliated on its outer margin and terminates in two claws ; the outer branch 

 is much shorter, its first joint bears a plumose seta at its apex, the second 

 is furnished with two setae at the extremity, one of them being similar to 

 the fringed seta? of the terminal joint, third joint very short and bearing six 

 setae, four of which are somewhat flattened and furnished with terminal 

 fringes of close-set cilia, while the other two are longer and plumose. 

 Three following pairs of feet almost similar, each branch 3-jointed. Fifth 

 pair with a short basal joint, with a seta at each angle of its apex ; second 

 joint flattened, ciliated on both margins, and bearing 5 long setae at its apex. 

 Caudal segments about as long as broad. Brady states that the fourth and 

 fifth abdominal segments are very short, in the specimens examined by me 

 the fourth was very short, but the fifth was very much longer, nearly as 

 long as broad. He also states that " the inner tail-seta? are nearly as long 

 as the body of the animal, outer about half as long, both finely aculeate in 

 their entire length." In the specimen figured by me the inner seta is not 

 much more than half the length of the body, and this proportional length is 

 very general in the individuals examined by me. The animal is usually 

 colourless, or according to Brady also " pale milky-white, often yellowish, 

 and sometimes distinctly banded with pale lilac or purple. Length,

Hab. Common in shore kelp and rock-pools near Dunedin ; also on 

 kelp in Paterson Inlet. 



An abundant species in European seas : occurring in the littoral 

 and laminarian zones, and often " taken by the tow-net in the open 

 sea." 



Genus Scutellidium, Claus. 



Body depressed, subovate. Anterior antennae 9-jointed, with very short 

 median joints : posterior 8-jointed, the inner branch short, 1- (? 4-) jointed. 

 Mandible palp large and complex, bearing numerous stout setiferous fila- 

 ments ; maxillary palp provided with two very long and stout ciliated 

 setae. Both pairs of foot-jaws forming clawed hands. First pair of feet
