Cubaris rugulosus. Miers, Ann. Mag. Nat. Hist. (ser. 4) xvu, p. 225, 
(1876). 
Moderately convex, rather loosely articulated, surface of the seg- 
ments uneven, faintly rugose. Head very broad and transverse, front 
margin revolute, first segment of the thorax with two slight depressions, 
diverging anteriorly, on the upper surface, sides of the segment 
directed obliquely backwards, so that the lower half of the posterior 
margin forms a distinct angle with the upper half. Succeeding seg- 
ments very narrow-transverse, each with an impressed line running 
parallel to its posterior margin, the second, third, fourth and fifth 
narrowed on the sides, which have their inferior margins rounded, the 
sixth and seventh segments broader on the sides, with the inferior 
margins truncate. Abdomen very short, with the segments (the last 
excepted) nearly linear-transverse, terminal segment much the broadest 
at base, with the sides at first suddenly converging, and then parallel. 
Caudal appendages with the inner (terminal) joint reaching to the end 
of the produced portion of the penultimate joint. Colour yellowish, 
margins of a darker colour and blotches of the same. Length 3 in.

Caudal appendages having two branches, both lateral, and small, 
and short styliform. The two branches of the caudal appendage are 
both situated on the inner margin of the base, one near the medial 
line of the abdomen, and the other on the inner side of the base, not 
far from the apex. The outer branch is visible in a dorsal view
