136 BIOLOGICAL SURVEY OF 



Lepidonotus Leach 



L. sQUAMATus (Liiine). (Mcintosh, 1900, p. 274, pi. 25, 

 fig. 1 ; Fauvel, 1923, p. 45, fig. 16f-j.) Perhaps the most abun- 

 dant scale worm in this Region. Found from low water to 

 239 feet, especially frequent at the lesser depths. Very abun- 

 dant among calcareous algae at S 43. Stations : The best 

 stations are D 19, 27, 56; S 4, 11, 14, 35, 39, 43, 50. Found 

 in all at 34 dredging and 15 shore stations. 



Aphroditidae 

 Aphrodita Linne 



A. HASTATA Moore. (Moore, 1905a, p. 295, figs. 1-4.) This 

 species is usually found on mixed bottoms containing much 

 mud, depth 30 to 239 feet. Specimens have been found 

 ranging in size from 15 to 230 mm. Adults are filled with 

 mature eggs and sperm in August. Their length of life must 

 be over 2 or 3 years to account for the great variation in 

 size. Stations : D 25, 35, 36, 38, 63, 71, 72, 83, 99, 103, 109, 

 118, 130, 144. The best are D 36 and 103. 



Sigalionidae 

 Pholoe Johnston 



P. MiNUTA (0. Fabricius). (Fauvel, 1923, p. 120, fig. 44a-h.) 

 This species ranges in size up to 5 mm. Found from low 

 water to 100 feet on bottoms containing mud. Rare at any 

 one station. The best stations were D 48, 59, 75. Stations : 

 D12, 14, 32, 38, 39, 46, 51, 54-56, 59, 70, 72, 73, 75, 94; S 4, 

 11, 12, 14, 19, 31, 34; PIOB. 



Nephthydidae 

 Nephthys Cuvier 



N. CAECA (O. Fabricius.) (Mcintosh, 1908, p. 9, pi. 66, fig. 3 ; 

 Fauvel, 1923, p. 365, fig. 142.) This species is found from 

 extreme low tide to 330 feet. It is most abundant in deep, 

 soft mud and among broken shells. The best stations are D 1, 

 81, 110, 112, 113, 125, 150, 151. Stations: Fifty dredging 

 stations and S 11, 25, 33, 35, 41, 43.
