I’lii-c'atoicid, so far as I (-an (llseover, having' setae of any kind upon 
this ramus. 
Ill view of all these facts, it seems ju'obable that it will beeoiue 
necessary to create a ik'av genus to receive the South African species, 
but ui)oii the whole, V. capcnsis may be regarded as approaching 
most nearly to the Australasian sul)*a1i)ine forms, while retaining 
certain characters undoubtedly primitive, many of these linking up 
with A »(/>/((, sop H.s‘, \FA)phrcaioici.LS and Pit reafoicopsis. 
Apart from P. wianamattensis, no undoubted fossil Phreatoicid 
seems to have been recognised, I have had, unfortunately, no access 
to the woi'k of Packhard, (pioted by (T(a>tfrey Smith, but that author s 
reconstruction of Aranthotelson stimpsoiii would serve, almost without 
moditication, for the aiu'estral Phreatoicid. The elongated head, 
body -with thirteen visible segments lu'actically of uniform size, the 
telson marked off from the last jileon segment, pleon-telson practically 
('(puilling ce])halon-]>eraeon (the elongate telson but an exaggeration 
of that of P. sjiiiwsHs), pleon probably not strongly compressed and 
■without downwardly develo])ed ])leura, the first antenna filiform and 
mod(M'ately long, without accessory flagellum, the second antenna 
without scale, with no trace of stalked eyes, the first peraeopod by 
way of becoming a gnathopod, peraeopods without exopodite not 
yet divid('d into two series, with distinct coxae and littl ' differentia- 
tion of more distal joints, jdeopods -with stout basal joint and equal 
lamelliform rami, the elongate, e(|ual and highly setose rami of the 
uropods, a walking form, but probably ca])ablo of feebly swimming, 
such a form might nuudi more justly be (dassed A\’ith the Phrea- 
toicidea than Avith the Ryncarida.
