NO. 1 HARTMAN : GONIADIDAE, GLYCERIDAE, NEPHTYIDAE 101 



Distribution. — N. magellanica is known in the Eastern Pacific Ocean 

 from southern California to the Strait of Magellan; it occurs also in 

 West Indian seas and Colombia and Venezuela. Its bathymetric range 

 is from low intertidal to 75 fms. 



Nephtys panamensis Monro 



Hartman, 1940, pp. 239-240, pi. 41, fig. 105, pi. 42, figs. 106-109. 



Collections not previously reported. — 667-37 ( 1 ) ; 936-39 ( 1 ) ; 

 945-39 (1); 1088-40 (2). 



The proboscis usually has only 3 longitudinal rows of papillae 

 (Monro, 1928, pp. 81-82, figs. 3-4). A specimen from station 667-37 

 has 6 to 8 rows but it agrees with the others in having a veiy long 

 median papilla. 



Distribution. — This occurs on the Pacific side of Panama, Costa 

 Rica and the Gulf of California, Mexico, in intertidal zones to 50 

 fms. 



Nephtys hombergi Audouin and Edwards 

 Plate 17, fig. 2 



Nephthys macandrewi Baird, 1873, p. 94. 

 Fauvel, 1923, p. 367, fig. 143. 



Material examined. — Holotype specimen of Nephthys macandrewi 

 Baird, from Corufia, Spain, in the British Museum of Natural History, 

 London, England. 



The everted proboscis has 22 rows of papillae distally and there is 

 a distinct middorsal one subdistally; the proximal surface is smooth. 

 Interramal cirri are recurved, first present from the fifth segment where 

 they are already large; they are continued back nearly to the end of the 

 body. The last 10 or more segments are regenerated in this individual. 

 The preacicular notopodial lobe is broadly incised (fig. 2) and acicular 

 lobes have a digitate elongation. Neuropodia have expansive oblique 

 postsetal lamellae. In all of these respects the specimen agrees with N. 

 hombergi Audouin and Edwards (see Fauvel, 1923, p. 367). 



Distribution. — This is known from western and southern Europe.
