Plate 87, fig. 3 a, animal, much enlarged, showing external and 

 internal ovaries, with the eggs bright blue; b, posterior antenna. 



South Pacific, latitude 43° south, longitude 78° 45' west, April 3, 

 1839; also (the specimen figured), on the Lagulhas Bank, latitude 

 35° 50' south, longitude 23° east, April 11, 1842. 



Length, one-eighth of an inch. Transparent, except the eggs, which 

 are rich blue ; there are slight opalescent colours in certain lights, and 

 the surface in one specimen was sparsely punctate with black dots. 

 The conspicilla are very large, so as to occupy the front margin ; and 

 the anterior antennae project laterally some distance behind the con- 

 spicilla. The anterior articulation of the cephalothorax is less dis- 

 tinct (as usual) than the following. The appendages to the first seg- 

 ment of the abdomen are oblong cylindrical, and terminate in two 

 unequal divergent setae. The eggs of the external ovaries were large, 

 and the bags did not extend quite as far as the extremity of the abdo- 

 men ; twenty or twenty-four eggs in each. The ovaries within extend 

 quite to the front of the animal. They are in four lines ; the two 

 inner are not half the length of the cephalothorax, and containing 

 eggs of smaller size than the others ; the two outer spread laterally, 

 or ramify in each of the segments, and also either side of the mouth ; 

 after reaching the front, they return back for a short distance along 

 the margin of the animal. 



The duct in the caudal lamellae was distinct, and some shreds were 

 observed externally at the extremity of each. 



Sapphirina elongata. 



Digitus antennarum posticarum tenuis, dimidio brevior quam articidus 

 2dus. Lamellce caudales latce, breviter ovatce, apice interno vix pro- 

 minulo, setts quatuor, totis dimidio lamellce brevioribus. Feminae : — 

 Corpus angusti elongatum, valde convexum. ConspiciUa f route insita.. 

 Abdomen 5-articulatum, segmento primo parvulo, secundo majore, sed 

 valde minor e quam sequens, sublunato. 



Finger of posterior antennae half shorter than second joint. Caudal 

 lamellae broad, short ovate, breadth more than half the length, 

 inner apex hardly prominent, setae four, all shorter than half the
