and from the twenty-eighth segment are found on all segments. He notes further that the elytra 
increase in size up to the twelfth pair; and then become smaller. In E. splendida there are twelve 
pairs of elytra, the last much the largest, borne on segment 24, but extending back so as to cover as 
far as greater part of segment 31, and the above generic description — that all of the posterior segments 
bear elytra — applies only if we regard the broad, flat expansion of the dorsal cirrus as an elytron (fig. 
Figs. 19-22 /). — Eulepis splendida. Fig. 19, Head, / 17. Fig. 20, First parapodium, x 23; d. dr. 'and r. cir., dorsal

21 ). This can hardly be the case, since it is found on all the cirrus-bearing segments, except the most 
anterior ones. In this respect these specimens do not agree with Grube’s diagnosis. They agree in so 
many other respects, however, that I have no hesitation in assigning them to this genus. Probably 
the loss of posterior elytra is correlated with the enormous development of the twelfth pair. 
Parapodia around head very much crowded together; the second and third segments fused 
dorsally, so that the second elytrophore apparently arises from anterior end of third segment. The 
first elytra completely cover the head. 
The first elytra were removed in order to draw the head, and were unfortunately lost before they 
could be drawn. A drawing of the seventh is 
given in fig. 22« and of the twelfth in fig. 22 b. 
These are drawn to the same scale, to show the 
increase in size from before backward. Except a 
small notch on outer border, the edge is entire. 
Their color is white, and they show, under the 
microscope, a finely granular texture. At ante^- 
rior edge of ventral ramus of parapodium is a 
dark spot. 
Body of 37 segments. Length, 37 mm. Width 
without parapodia, 3 mm. ; with parapodia, 5 mm. 
The single entire specimen had one anal cirrus.

Head rounded (fig. 23) . Antenna small, 
globular, on a short stalk. Tentacles reaching a 
little beyond tip of antenna, rising from under 
surface of head. Palps long, smooth, closely appressed in middle line. Head thickly marked with 
yellowish brown. Two dark spots (eyes?) near base and one toward apex just behind base of antenna. 
All appendages around the head very much crowded together. The anterior elytra completed cover 
the head, their elytrophores touching on median line. An anterior process from base of elytrophore
