. Bulletin of the Museum of Comparative Zoology at Harvard College. Zoology. Figs. 1-2. Deposits from sole of Psolus squamalus Diiben and Koren. Figs. 3-5. Deposits from sole of Psolus valvatus Oestergren. From Mortensen's Denmark's Fauna (X 145). Remarks.— Ekman has been of the opinion that this species is the young of P. squamatus. The text-figures clearly show the difference between the two species. Moreover, P. squamatus has never been col- lected in the western part of the Atlantic Ocean, where P. valvatus has been found. The few older records refer all to P. fabrieii (see p. 192). Psolus

Only one large specimen is at hand, namely the same which Theel very doubtfully referred to operculaius, calling attention to the fact that it had some pecuHar cups beside the grains on the dorsal side. A large specimen, the sole about 4 cm in length. Dorsal side very high, vaulted; scales thin, resembhng those oi Psolus squamatus; about 6 dorsal scales between oral and anal scales; oral opening closed by 5 triangular valves; inside these, 5 radial " teeth" and outside, 5 small.
