Thomson. — On New Zealand Cmstacca. 261 



Hon') of 19th January, 1886 (p. 4). Mr. Stebbing has very fully 

 described and figured the male in the Transactions of the same 

 society, vol. xii., p. 202, pi. xxxix. 



The following is a brief description of the female : — 



Mouth-organs as in male. Upper antennae with the fia- 

 gellum only 5-jointed ; lower with the flagellum 12-jointed. 



Gnathopod of the 1st pair (fig. 4) almost similar to the 

 same limb in the male, but with fewer spines on the front 

 margin of the first joint, and with the finger somew^hat longer 

 than the hand. 



Gnathopod of the 2nd pair (figs. 5 and 6) : First free 

 joint nearly as long as all the rest together, with very numerous 

 spines on the front margin, and almost smooth behind. Wrist 

 and hand subeqiial in length, former rounded and slightly 

 spinous below ; hand laterally flattened, beset with short 

 spines on both sides, with a produced rounded palm ; finger 

 almost obsolete, represented by a minute lobe at the extremity 

 of the upper side of the hand. The three anterior pairs of 

 peraeopoda very similar to those of the male ; those of the 

 4th pair having the 4th joint straight, with the front and 

 back margins nearly parallel, and without the prominence so 

 characteristic of some forms of the male. 



34. Jdegamcera fasciculata, mihi. 



Gathered in abundance at Waiw^era and Auckland Harbour, 

 mostly on the under sides of wet stones betw'een tide-marks. 



Z6. 2Ioera sub-carinata, Haswell. 



Dredged in the Bay of Islands at 8 fathoms. Also 

 received from Waipapapa Point, where it was gathered by Mr. 

 J. F. Erecson. 



39. Melita temdcornis, Dana. 



Found in abundance, along with No. 34, at Waiwera and 

 Auckland ; also dredged in the Bay of Islands, where Dana 

 originally obtained it. It is a common littoral species. 



41. Harmonia crassijpes, Haswell. 



A specimen, apparently referable to this species, was 

 among my Bay of Islands dredgings, but the original descrip- 

 tion and di-awing are so imperfect as to make identification 

 difficult. It seems to me also that Mr. Haswell has not 

 shown sufficiently good grounds for separating this species 

 under a distinct generic appellation honi Spence Bate's genus 

 Eurystheus, to which I think it ought to be reunited. 



43. Aora ti/plca, Kroyer. 



Very abundant in dredgings in the Bay of Islands. This 

 is a very variable species. In one male specimen the right
