a faint tuberculate longitudinal ridge on each side of posterior half; on each side 
of anterior half is an elongate shallow depression. Pseudorostral lobes not meet- 
ing in front of ocular lobe, which is rather narrow with large and partly pig- 
mented lenses. Antennal notch deep and angle subacute, rounded. 
Part of first pedigerous somite visible; second to fifth somites each with a 
low, median dorsal carina; second large, anteriorly elevated to highest level of 
dorsum of carapace, thence sloping steeply downwards; third short dorsally but 
expanded backwards infero-laterally ; fourth and fifth somites narrower and with 
sides tumid. 

Fig. 59. Cyclaspis sabulosa, paratype male; A, lateral view; B, cephalothorax and GC, 
anterior portion of carapace, from above (A and B, X 19; ©, X 50). 
Pleon somites each with a low median carina and sparsely studded with small 
tubercles; lateral articular processes well-developed. Telsonic somite with an 
abrupt dorsal incision at. junction of fused telson. 
Basis of third maxilliped strongly geniculate, almost. twice as long as re- 
mainder of limb, with outer apical portion expanded, the large lobe with plumose 
apical setae; merus wide, with outer lobe reaching distal margin of carpus, which 
is widest anteriorly and is as long as propodus and dactylus together, but shorter 
than merus. 
First peraeopods with carpus reaching beyond level of antennal angle; basis 
about one-fifth as long again as rest of limb, with inner apical angle produced for- 
wards to about middle of length of ischium, and with a long plumose seta at ex- 
ternal distal angle (reaching to apex of merus), and a shorter subapical seta near 
inner angle; carpus, propodus and dactylus subequal in length, and to ischium 
and merus together. 
Second peraeopod with basis as long as remaining joints together; ischium
