an inadequate idea of the richness of the fauna. Eeinvestigation would 

 doubtless show the fauna to be as well represented by numerous species, 

 as it obviously is by innumerable individuals, the sand flats presenting 

 a most striking illustration of the wealth of Annelid life that may be 

 supported under the exceptionally favorable conditions here prevailing. 



Family AMPHINOMID^. 



AMPHINOME Brugnieres. 



Amphinome rostrata Quatrefages. 



QUATREFAGES. Hist. Nat. des Annelis, vol. 1, i>. 393. 



Small and apparently immature specimens of Amphinome were found 

 on several occasions among the stalked barnacles upon driftwood 

 brought into the harbor by certain winds, and referred, with consid- 

 erable doubt, to the form Quatrefages seems to have had for the above 

 description. 



The coloring of the body suggests a protective resemblance to the 

 stalks of the barnacles among which the Annelid lies concealed, though 

 Langerhans thinks that the conspicuous colors of certain members of 

 this family are useful as a warning signal, some having, he says, poison- 

 ous setie. 



Family POLY^NOID^.

Small specimens are not uncommon in material dredged in shallow 

 water, both inside and outside of the inlet, and were taken both in 1884 

 and 1885. 



Lepidonotus variabilis Webster. 



Webster. Annel. Cbiet. Virginian Coast, p. 58, PI. vii, Figs. 6-11 ; PI. ii. Figs. 12-14. 

 This occurs upon oyster shells, etc., in shallow water. It was taken 

 at " Green Rock," in June, among hydroids; upon the bottom of a float- 

 ing scow, off Schackelford Bank, in August ; near " Horse Island," and 

 among sponges dredged near Moorhead City, in June.

Body long, much flattened; set! gerous somites, 34. Cephalic lobe 

 deeply cleft. The two lobes swollen and with the acuminate tips sharply 

 distinguished. Anterior eyes larger than posterior, opposite posterior
