 pro.ximallv on this bristle, a protuberance of about the same type as (J. \\ . All LLKI! observed 

 on Ph. Icvis (1894, pi. 3, lig. 31). 



Mandible (fig. 11): — This is very like that of I'li. ( I'li.J tjlobum. I* r o t o p o d i t e: 

 The basale has eight or nine bristles ventrally, of about the same length as in the species just 

 mentioned. Dorsally this joint has, besides the two distal bristles, five (sometimes four) bristles 

 on the distal half. As in /'//. i Ph.) globosa the shorter distal bristle is about as long as the 

 anterior side of the first endopodite joint, the longer one is about twice as long. The remaining 

 five are subequal and about as long as the shorter distal bristle. In most cases all tliese bristles 

 of this joint have a wreath of long, stiff secondary bristles at the middle ajid exceedingly fine 

 hairs distally; sometimes, however, there may be no wreath on some of them. Endopo- 

 dite: The second joint differs from Ph. (Ph.) glohusa by having five, sometimes even six, 

 bristles in tlie anterior-proximal group. 



Maxilla: — This is very like that oi Ph. (Ph.) globosa. We may note: P r o t o- 

 podite: On the boundary between the protopodite and the endopodite there are on the 

 anterior edge of the palp two bristles with short hairs, usually subequa! and varying somewhat 

 in length, sometimes only about half as long as the first endopodite joint, sometimes about as 

 long as the corresponding bristle in Ph. (Ph.) globosa. On one specimen three of these 

 bristles were observed in this place on one maxilla. Exopodite: The equipment 

 of the three bristles is rather variable; the short bristle often seems to be without 

 long secondary bristles. Endopodite: End joint: This has usually, as in Ph. (Ph.) 

 globosa, four, sometimes five, a-bristles; on one specimen three b-bristles were observed, 

 two of which were powerful; four or five, usually four c-bristles; the three d-bristles are 

 sometimes subequal, in most cases, however, the relation between their lengths is the same 

 as in Ph. (Ph.) globosa. 



Fifth limb: — This is quite like this appendage in Ph. (Ph.) globosa. 



Sixth limb: — This is very like that of PJi. (Ph.) globosa; we may note that the 

 second joint of the exopodite has 28 — 33 bristles. 



Seventh limb (fig. 13): — This has about the same relative length as the corre- 

 sponding appendage in Ph. (Ph.) globosa. The cleaning bristles are relatively few, usually ten, 

 sometimes eleven, of moderate, somewhat varying length. UsuaUy six of these are situated 

 dorsally, three close together distally and three scattered somewhat proximally of the former. 

 Four, sometimes five, are situated ventrally, two close together distally and two or three somewhat 

 proxima lly of th e former. EquijDment of the cleaning bristles : Three to six bells cut o ff transvcrsally
