On this part thoro is also an plonpattHl little jxH-kot, situated alxnit |)iirallcl to the inaryiii of tlio 

 slioll: on till' ('ili»o of thrs pocket tliere are often a few extremely sliort i)ristles; fliis pocket is 

 often full ef all sorts of dirt. For tlie selva<!;e see fi«i;s. 4 and 5. The in;ir<.Mrinl liristles on the 

 rostral selvajje are ratlier short. Aecordiiii; to (I. ( ). Sahs's stateineiil the shell has a pali' 

 yellowish colour. 



First a n t c nMi a (fig. 7): — Of the three bristles on the second joint the posterior 

 one. which is somewhat longer than the two others, is usually as loiiy as the total length of the 

 third and fourth joints. The third joint has three or four, usually three, bristles anteriorly; 

 the anterior one of these is rather short, usually not quite so long as this joint, the others are 

 subequal and in most cases about as long as the Inurth joint. The posterior bristle on this joi?it 

 is short, about half the length of the next joint or somewhat longer. The fourth joint has the 

 same bristles as in Ph. (Ph.) globosa; their length is, however, on the average, somewhat less 

 than in this species, the two medial ones and the four posterior ones especially are rather short. 

 The bristle on the fifth joint is about the same length as this joint. The a-bristle on the end joint 

 is about the same as the anterior bristle on the fourth joint. Most of these bristles have one or 

 a few wreaths of long, stiff secondary bristles at the middh': these are, however, often missing 

 on the short anterior bristle and the posterior one on the third joint. Variation in the secondary 

 bristles may, however, be observed; in the length of the bristles so far mentioned I have also 

 observed some, though only rather slight, variation. The bristles of the end joint (fig. 8) have 

 the same equipment as in Pli. (Ph.) glohosa, i. e. the b-bristle with one proximal and three distal 

 sensorial filaments, the c-bristles with five proximal anil four distal sensorial filaments, the 

 f- and g-bristles with four and three proximal sensorial filaments respectively and four distal 

 sensorial filaments; in one specimen six proximal filaments were observed on one c-bristlc on 

 the antenna of one side. The pilosity is about the same as in Ph. (Ph.) globosa. 



Second antenna: — Exopodite: This is very like that of Ph. (Ph.) globosa. The 

 proportion between the length of the first joint and the total length of all the following joints 

 is about 43 : 37. In some cases females with rather large eggs in the brood chamber were dis- 

 covered with their long natatory bristles quite intact; in most cases, however, these natatory 

 bristles were broken off as in Ph. (Ph.) globosa. This ma}- perhaps indicate that this character, 

 of having the long natatory bristles broken off is not completely fixed in this species. There 

 seem sometimes to be no basal spines at all on the second, or the second and third, joints. In 

 most cases the basal spines are simple; sometimes, however, they have two or three points. 

 In some cases one or more small spines may be observed close to one or more of the basal spines 

 (cf. p. 385 above). Endopodite (figs. 9 and ID): The first joint has quite the same 

 equipment of bristles as this joint in Ph. (Ph.) globosa. The second joint has several bristles 

 ventrally: One rather long one — its length varies somewhat, however — situated somewhat 

 proximally of the middle of the joint; this bristle is furnished at the middle with several irregular 

 wreaths of long, stiff secondary bristles and with short hairs distally. Distally of this bristle 

 there are in most cases three moderately long bristles; on one specimen only two bristles were 

 observed on the antenna of one side; whether the third had been broken off could not be decided 

 with any certainty, though probably it had not been. G. S. BhaijY and A. M. NORMAN, 1896
