432 DR. G. S. BRADY ON NEW OR 



and calcareous, the soft ones probably imperfectly matured after moulting. The types 

 of the species were described by me from specimens taken amongst the South-Sea 

 Islands, and do not differ from the New Zealand examples except in being rather 

 larger. 



Asteeope qvjadrata, sp. n. (Plate XLV. figs. 17-21.) 



In general appearance this is very like A. australis, but it is somewhat smaller, and seen 

 dorsally has much more obtuse extremities, having almost parallel lateral margins ; the 

 inner antennal branch of the male (fig. 19) is very broadly clawed, and the larger ungues 

 of the post-abdominal laminae in the female (fig. 21) are not only finely pectinated, but 

 bear a few longer interspersed setse — about five on the last and three on the penultimate 

 unguis ; in the male, however, of which only one mutilated specimen was seen, there 

 is only a simple pectination. Shell extremely thin and membranous. Length 1*3 mm. 



llab. Lyttelton Harbour, dredged in a depth of 1-5 fathoms. 



Asteeope geisea, sp. n. (Plate XLIII. figs. 9-14.) 



Shell of the female, seen from the side, elongated, elliptical (fig. 9), height scarcely 

 as much as half the length, and nearly equal throughout ; extremities evenly rounded, 

 the posterior rather the narrower of the two ; dorsal and ventral margins evenly and 

 very slightly curvate. Seen from above (fig. 10) the outline is narrowly ovate, the width 

 equal to two-fifths of the length, slightly tapered towards the front, broader and 

 rounded off behind. Shell chitinous, flexible, perfectly smooth, colour greyish. 

 Length 2 - 8 mm. Frontal tentacle cylindrical, its terminal joint slightly dilated at 

 the base; secondary branch of the antenna (fig. 12) small, simple, with a small apical 

 seta ; spines of the post-abdominal laminae (fig. 14) long, slender, very delicately ciliated. 

 Claw of the secondary antennal branch in the male (fig. 11) much thickened and 

 dilated at its base. 



Hab. Akaroa Harbour ; many specimens dredged in a depth of 6 fathoms. Only one 

 male could be found, and this was a good deal damaged; its only marked peculiarity, 

 so far as could be made out, was the extreme length of the antennular setse. 



Genus Ctclasteeope G. S. Brady. 

 Cyclasterope Brady (5), p. 85. 



Ctclasteeope ovulum, sp. n. (Plate XLIII. figs. 24-30.) 



Shell of the female (figs. 24, 25), seen from the side, nearly circular, slightly narrowed 

 and produced in front, antennal notch small and shallow ; seen from above, ovate, widest 

 in the middle, twice as long as broad, subacuminate in front, narrowly rounded behind. 

 Shell dense and calcareous, smooth, finely punctate. Length 8 mm., height 6 - 6 mm.
