M . Murano. Remarks .ffli s specimen clearly belongs to the genus Amblyops because it has separated plate-like eyes (Fig. 22A), antennal scales with the apex of the blade at the same level as the distolateral denticle (Fig. 22B), and four-segmented antennal peduncles showing the characteristic connection between the second and third segments (Fig. 22B). It differs from all the known species of the genus in the following respects: (1) the papilliform projection on the anterior margin of the eyeplate is very small and hardly detectable (Fig. 22A); (2) the antennal scale is 3.0 times as long as wide (Fig. 22B); (3) the telson is rather truncate and 1.6 times as long as its basal width (Fig. 22C); and (4) the telson is armed with about 10 spines on the posterior three- hs of the lateral margin and ve pairs of spines on the posterior margin, of which the innermost pair is minute (Fig. 22C, D). fflere is no doubt that this specimen represents an undescribed species, but the formal description is postponed because of the specimen’s poor condition.
