Actza spinosissima Borrapaltte. 
Actea spinosissima BORRADAILE, Fauna Maldive Arch., I. part 8. p. 256. fig. 55, 1902. 
Nallandu, at anchorage, 24 fathoms, January 18 ; two young. 
Xanthias alcocki, sp. nov. 
Figs. 9-10. 
The surface of the carapace is granular, the granules coarse on the anterior 
and antero-lateral portions, very fine on the posterior part. Fronto-orbital 
region marked off by a sinuous groove. Regions well delimited. There is a 
short transverse crest on each epigastric, protogastric, hepatic and anterior 
branchial region. 
The front is marked by a double edge, the lower or true edge not visible in 
a strictly dorsal view, outer angle very slightly marked. Notches of supra- 
orbital margin minute. 
Antero-lateral margin cut into four teeth besides the inconspicuous outer 
angle of the orbit; the first and fourth teeth are very small, the second and 
third of good size, triangular, the tip of the second pointing a little forward, 
the third directed outward. <A subhepatic protuberance is visible between the 
orbital and the first antero-lateral tooth. 
The chelipeds in the female are nearly equal, stout, less than twice the 
length of the carapace. Outer surface covered with scaly granules. Merus 
nearly hidden under the carapace, margins finely serrulate. Carpus with a 
few larger granules. Granules of hand larger above than below, some of them 
disposed to form longitudinal rows. Fingers rather long, deflexed, grooved, 
tips crossing ; light brown in alcohol, the color on the pollex not reaching 
quite to the palm; dactylus of right or larger hand with a large tooth at its 
base. 
Ambulatory legs finely granular ; upper margins of meral and carpal joints 
serrulate. Dactyli pubescent, propodal joints sparsely so. 
Dimensions. — Length of carapace of female, 3 mm. ; width, 4.4 mm. 
Type locality. — Nallandu, 24 fathoms, at anchorage, January 18; one mature 
and one young female. 
Pilumnus woodworthi, sp. nov. 
Figs. 11-12. 
Carapace nearly three-fourths as long as broad, deeply areolated, covered 
with a short dense pubescence mixed with longer hairs; when this is removed, 
fine granules may be seen on the anterior portion of the gastric region and
