. Bulletin of the Museum of Comparative Zoology at Harvard College. Zoology. LOOMIS: NEW MILLIPEDS FROM CUBA 453 across the dorsum on the anterior half of the segments. The gonopods indicate affinity with M. belonanus Chamberhn, a Hghter colored species. Description. Length 20 to 25 mm; the males smaller than the females; number of segments 44 to 47. Color in general almost black with small but conspicuous white markings; head with labral region light brown, elsewhere black; first segment black except for a narrow, sharply defined, white anterior.
