Comprehensive Description

Description

LIMA (Limatula) HODGSONI.

 

(Pl. III., figs. 8-8b.)

 

 

Shell oblong, oblique, narrow above, rather convex, thin, white; anterior side more curved than the posterior; ventral margin arcuate, curving obliquely upwards behind; surface ornamented with 30-35 fine ribs, which are very finely scaled by being crossed by the lines of growth (fig. 8b); the ribs are rather broader than the inter­vening grooves, and do not occur on the auricles, which are only sculptured with the incremental striæ; the scales are very close-set, and only very little elevated; interior of the valves radiately sulcate, slightly denticulate along the lower margin; umbones central, a little prominent above the ligamental area, which is very narrow diamond-shaped.

 

Length, 27.5 millim.; height, 35; diam., 20.

 

Winter Quarters, various dates, 10-130 fathoms, also off Coulman Island, 100 fathoms.

 

Allied to Lima pygmæa Philippi, but much larger, of a rather different form, being broader beneath and much more contracted above. The ribs, also, in the present species are broader and much more beautifully squamate.”
