of rounded two-branched lobes. The minute abdomen is very 

 difficult to distinguish ; I could only recognize one articulation, 

 and its extremity appeared to be two-lobed. Oviferous tubes 

 rather stout, hardly exceeding the length of the thick part of 

 the thorax. 



Length of body, 6-8mm. ; including the oviferous tubes, 

 9-lOmm. 



Hab. Taken from the mouth of the porcupine-fish — Chilo- 

 nnycterus jaculiferus — by Mr. A. Hamilton, of Napier, to whom 

 I am indebted for much assistance in working out the Crustacea 

 of these seas.

 and 6a. 



Body long and narrow. Head laterally compressed, elon- 

 gated, three times as long as broad when seen in front. Seen 

 laterally it is rounded behind, and in the middle of the front 

 margin protrudes a little at the point of attachment of the 

 mouth-organs. The front part of the thorax is hardly broader 

 than the neck, and is separated from it by a short constricted 

 part or neck. The posterior division of the body is somewhat 

 wider, and bears two pairs of elongated fleshy lobes which are 

 considerably curved inwards towards the median line. An- 

 tenna of first pair small and distinct, rather widely separated 

 at the base and standing out backwards like minute horns. 

 The second pair are produced a little forward in the form of 

 two curved hooks. The mouth-organs are rather prominent. 

 Both pairs of thoracic legs are elongated, and have the 

 branches well defined and projecting somewhat widely to the 

 sides. Abdomen not seen. Oviferous tubes short and stout, 

 not half as long as the body. 



Hab. Taken on the gills of the ling — Genypterus blacoiles.

 a- and b. 



Body very short and thick. Seen from the front it ex- 

 hibits three pairs of fleshy obtuse lobes directed inwards and 

 downwards ; above these the head stands out somewhat dis- 

 tinctly. Looked at from the side the lateral lobes are seen to 

 project prominently forward, while along the back are three 

 large fleshy obtuse lobes directed posteriorly and correspond- 

 ing to those of the sides. Behind the head also is a rounded 

 protuberance. The antennae are closely approximated, and 

 broadly falcate in shape, lying close to the front of the head 

 and not reaching past its lateral margins. They project for- 

 ward to a considerable extent, so that the buccal portion is 

 somewhat concave. Tlie two pairs of thoracic limbs are
