. Bulletin of the Museum of Comparative Zoology at Harvard College. Zoology. LOOMIS: PUERTO RICAN AND DOMINICAN MILLIPEDS 45 middle of the dorsum, is a small elongate light spot either transverse or slightly inclined backward from the outer end; in younger specimens the light colored areas are larger but with less distinct limits. Head with median furrow of vertex short and faint; eyes the size of the antennal socket or smaller, the ocelli relatively few, small and not distinctly elevated above surface of head, numbering 21 to 23 in five Fig. 14. Microspirobolus tenuipes. a, Gonopods, anterior view; b, Gono- pods, posterior view. First segment narrowing on each side to the rounded-truncate lateral limits and with a raised rim extending from behind the eye around to the posterior margin, the front margin below the eye straight or only slightly emarginate. Ensuing segments with a strong sulcus marking the transverse constriction from segment 2 to the last five segments where the constriction vanishes; pores of moderate size surrounded by a small impressed ring; dorsal surface of segments smooth and shining; ventral striae fine and confined to the lower surfaces except on a few of the anterior segments where short striae immediately be- hind the transverse sulcus exceed the tips of the legs but do not ap- proach close to the line of pores. Last segment produced to an acute point not surpassing the valves, the thick margins of which meet in a deep groove; preanal scale large, subtriangular, the sides straight to the rounded-acute apex. Gonopods very thin, their anterior and posterior aspect shown in figure 14, a and b. Ventral surface of segment 7 of the male raised at middle into a very thin, backwardly curved, lip-like ridge, broad and low on either Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the o
