HALE—AUSTRALIAN CUMACEA u7 
Fossorial lees as in C, crelata with the apical seta of the carpus stont. 
Uropods long, the peduncle more than half as long again as telsonie somite; 
inner edge with a row of long plumose setae on proximal half; these are followed 
by a series of more slender plumose selac and a parallel row of shorter sleuder 
spines; exopud a Little longer than endopod and almost as long as pedunele, with 
a row of seven plumose setae on inner edge, leaving posterior half unfurnished ; 
inner margin of endopod with six slender spines near base, followed by a row of 
seventeen small short spines, increasing gradually in length backwards, ul lowy- 
ing ibe distal third of the ramus unarmed. 
Colour white, with brown chromatophores on the anterior dorsal depressions 
of carapace, the psendorostral lohes, the fourth pedigerons and first five pleon 
somites, 
Length 6-45 m.m. 
Loc. South Australia: Waterhouse Bay, east end of Thistle [s., 8 to 8.30 p.n., 
and Dangerons Reef, 4 fath., 8 to 8.30 p.m, (K. Sheard, submarine light, Mar. 
1941). Type in South Australian Mnseum, Reg. No. C. 2328. 
Ouly males were secured, As with other similar forms taken after darls it 
is probable that the colour pattern is more apparent in daytime. The spines on 
the inner margin of the endopod vary little in the available material, five to six 
proximal slender spines followed by a series of sixteen to seventeen, C. granulosa 
is rather close to eretata, partiealarly to the South Australian form of the last- 
named, but the roughened appearance of the carapace, due to the granulation, 
cannot pass niuoticed, while the propodus of the first peraeopods, when the two 
species are plaeed side by side, is easily seen fo be relatively shorter, 
CychAsriIs CONCINNA sp. nov, 
Adult male. Tnteenment asin pura, A fine sharp median carina on carapace, 
exposed pecligerous, and pleon somites, 
Carapace with dorsal margin slightly and evenly arehed from reat to hase 
of ocular lobe; iwo-sevenths of total length of animal and with its depth much 
more than half its length; narrow, the width considerably less than depth and 
less than half the length, Antennal noteh moderately deep, with a short shallow 
groove running back from it; antennal tooth subaente withord autennal ridge, 
Pseudorostral lobes reaching apex of ocular lobe but barely meeting in advanee 
of it, Oenlar lobe subtriangular, rounded anteriorly and constricted at base; as 
wide as long and with nine laree lenses, 
Exposed pedigerons somites together more than half as long as carapace; 
second somite rather short with dorsal edge sloping steeply down from dorsal 
contour of carapace. 
Pleon as in pur. 
Third maxilliped with basis twice as long as reimainmg joints together, and 
with a long narrow apical lobe, one-third as long as rest of basis and capped with 
plumose setae; merus longer than carpus with a wide lobe reaching level of apex 
of latter; ischinm relatively long subequal in length to the earpus, whieh is widest 
anteriorly and as long as propodus and dactylus Logether. 
First pecacopod with carpus not reaching level of antennal angle; basis more 
than half as long again as rest of limb, with inner apical angle rounded, barely 
produced, there being present only a minute tooth; external angle with a long 
plumose seta, reaching beyond middle of length of carpus; carpus a liltle longer 
than propodus, which is distinetly longer than dactylus.
