276 CALMAM 



a capacious tube lined by an invagination of the chitinous cuticle, 

 the protuberance interpreted as the rudiment of the second 

 maxilla forming the lower or posterior lip of this orifice. Un- 

 fortunately, these tubes were not discovered till the soft parts of 

 the head had been removed by caustic potash, so that we are 

 unable to say anything as to their connections inside the body. 

 This is the more to be regretted since we know of nothing anal- 

 ogous to these organs, not only in the Epicaridca but even among 

 the JMalacostraca. 



The maxillipeds are similar to those of Pala^gygc but some- 

 what narrower. Each consists of a flat, roughly quadrangular 

 plate partially divided into two parts by an oblique line. The 

 posterior part has its external angle rounded and pointed as in 

 Pal(Egyge Borrei^ and the antero-internal angle is produced. 

 The anterior margin of the maxilliped bears a few setae, and at 

 its inner angle is articulated the small ''palp," also setose. 



Posteriorly, the lower surface of the head terminates in a 

 freely projecting lamina, the '' linibc postericur' of Giard and 

 Bonnier. * In the present species this lamina is cut up into a 

 fringe of digitate processes commencing on each side a little way 

 from the middle line and increasing in size outwards. Exter- 

 nally, on each side the lamina is produced into a long process, 

 narrowing gradually from its base to a rounded tip, turned 

 inwards and extending beyond the middle line. In Palcegyge 

 there are two pairs of shorter processes and no fringe of minute 

 digitations. 



The thoracic legs are all similar and of the usual structure. 

 The "adhesive cushions" present on the proximal segments of 

 the first pair in Palcegygc are here absent. The oostegites or 

 brood lamellae were unfortunately injured in the single speci- 

 men found. The usual five pairs are present and are much 

 larger than in Palcegyge Borrci, all the pairs except, perhaps, the 

 third and fourth, overlapping across the median line. The first 

 pair are, as usual, of somewhat complex form. Roughly 

 quadrilateral in shape, the posterior corner is produced into a 

 hook-like process directed inwards. A little behind the middle 

 of its length the lamella is crossed by a transverse fold, form-
