botli iimev an<l outer nun'iiiii.s niul nn ai)ieal wet of fourteen curved 
setae and two inner ])himose setae, an arranj>'euieiit closely paral- 
leled in Xroni phorf/iis spniccri (l!H)(Jji, PI. -10. Pi«'. Mil}. 
Thr ma.rillipcd (PI. \'ni. Pi^'. 6) has somewhat narrow inner 
plate with 'A a])ical spine-teeth; the hroa<h'r outer ])late has six apical 
curved setae’ (spine-teeth), somewhat more slender setae forming' a 
fringe along the inner margin of this ])late ; proxinially there are 
three long straight s(dae. 
The two (inathopods (id. ^■1I1. Fig. 1) are alike, not very strong 
and. appartmtly similar in both sexes. In these (and in the perae- 
ojmiix 1 and '2) the second joint is of narrow oblong sha])e, its pos- 
terioi- margin ln>aring a number of elongate Jlexil>le setae. The ]ialin 
r> (|uite obli(ju(\ has a sharp dentate edge and is guarded by sjiines 
and setae (PI. \ III. Fig. 7a). The legs generally are slender* a 
slight widtming of the second joint of pemeopodn 3 — 5 ])roducing a 
nan-owly oval structure. The shallowness of the side plates d — 7 
exposes a narrow distal ])ortion of the first joint. 
The ph‘(>pnds are biramous, of imxlerate hmgth, with unecpial 
rami, tin* third ]>air distinctly shorter than the preceding. 
Tlie iiropod.s (Pi. \'1II. Fig. 1) consists of a stout peduncle with 
a ]>air of slender and uiuMpial rami, armed with s])ines. In the first 
ami. second uropods it is the inmu' ramus which is the longer. In 
uro]>od 1 the pedumde is half as long again as the longer ramus and 
twice as long as tlie <mter ramus. The second and third uropods have 
Ihe peduncle snbe<|ual in length to the longer rami. The third 
iiro}iod (PI. Fig. 9) has the inner ramus rei»resented by a small 
scale whi(di lu'ais neither sjtine nor setae aiid reaches a length 
barely a third, of the pmluncle. The spincfi on telson (PI. VIII. .Fig. 
10) and uro]K)d. as already noted, are ])eculiar, being stout, notched 
near the a]H‘x to receive a slender curved ciliuin. This form of 
s])ine is (,fide Stebbing. 1906. pn. .‘!72-37.'l) apparently of constant 
occui'rence. in sjuades of the genus Crai}(fO)ii/.r. Of the setae found, 
in Protocraiii/ntnpr fottfiindis^ upon the iieraeopods some are of this 
caaracter as are the few setae (K-curriug upon the basal joints of 
rl'.e i)ieopods (the long setae upon the rami of the pleopods are 
plumose), but most of the setae upon tlie legs as well as those near 
tlie ventral margins of the side-plates and pleon segments appear 
to be siinj)le setae. 
Keinarks. As noted above, the affinities of this species seem 
to be in nearly eipial degTee with the forms grouped under 
"As an ahnorn.al develoinnent, one specimen showed the 1st peraeo- 
pods as stout and as long as the Ith or 6th.
