specimen in the Indian Museum was taken at the Andamans by the late Dr. W. T. 
Blanford and is figured in the ‘‘ Investigator ” Illustrations. It is probably immature. 
As we have only one small specimen I have quoted largely from Hoek in the description 
of the species. 
Pœcilasma minutum, Gruvel. 
P. minutum, Gruvel, Trans. Linn. Soc. (2), vol. viii, p. 288, pi. xxiv, fig. 5 (1902), 
Mon. Cirr., p. 120, fig. 138 (1905). 
Capitueum somewhat broadly ovate, pointed above, varying in proportions con- 
siderably. Valves six, delicate and translucent, not very closely approximate above. 
T ergum triangular, the anterior part of the scutal margin deeply excavated to receive 
the apex of the occludent segment of the scutum, the umbo surrounded by an opaque, 
sculptured area. Carina narrow, not reaching the level of the apex of the carinal 
segment of the scutum above, broadening out slightly at the base and concave on the 
sides, terminating in a broadly oval transverse disk below, generally with a distinct 
dorsal ridge, and sometimes with a subterminal tooth above. Scutum split into two 
segments, with an opaque sculptured area surrounding the umbo at the base; the 
occludent segment much broader above than at the base, bluntly pointed or rounded 
when in contact with the tergum, the arc of the inner edge having a wider radius 
than that of the occludent margin ; the carinal segment broad, convex outwards, 
without vertical ridges, its tergal margin straight, the carinal margin broadly 
arched, the basal margin not distinctly marked off from the carinal, the occludent 
margin corresponding with the inner margin of the occludent segment, with which 
it is in close contact. 
Peduncle very variable, often short and thick, sometimes longer than the 
capitulum and relatively slender, bearing numerous little round, yellowish chitinous 
plates, which are sometimes minute and inconspicuous. 
Cirri, etc. — First cirrus widely separated from the second, by no means broad, 
the anterior ramus reaching nearly to the tip of the penultimate joint of the pos- 
terior, the two distal joints of each ramus bearing a terminal circle of stout bristles 
and an anterior fringe of similar bristles, which is extended down the margin of the 
next one or two joints and disappears gradually towards the base of the ramus. 
Other cirri long and slender, bearing on their anterior margin numerous long, slender 
hairs, and at the distal extremity of the posterior margin of each joint a sparse 
bunch of similar hairs. Anal appendages slender, of variable length, falling short 
of, reaching or passing the basal joint of the sixth cirri, bearing at the tip a number 
of very long bristles, which extend a short distance down the posterior margin. 
Penis slender, moderately long, minutely annulated, pointed, bearing a short process 
on the dorsal surface near the tip and a few scattered hairs near the base. 
Mouth parts. — Lahrum not bullate, bearing a row of minute equal, triangular 
teeth. Outer maxilla long and moderately broad, spatulate, bluntly rounded 
at the tip, bearing a row of short, stout spines on the distal third of the external 
surface. The palpi short, bluntly pointed, bearing a somewhat sparse fringe of stiff'
