NO. 1 HARTMAN : POLYCHAETOUS ANNELIDS 159 



those farther back (pi, 9, fig. 213), but in some of the latter it tends 

 to stand more or less obliquely upward, whereas in anterior segments the 

 postsetal lobe is directed laterally. Posterior parapodia have typically 

 only 2 yellow acicula and usually lack limbate setae, though an occasional 

 slender one may accompany the simple, hooded hooks. 



Mandibles are large, strong, the base slightly incised (pi. 9, fig. 

 214) ; maxillae are likewise strong. The carriers are broad, laterally in- 

 cised, and frayed at their base (pi. 9, fig. 215). Forceps are falcate; 

 maxilla II has 4 teeth right, 5 left, or 6 right and 5 left, the distalmost 

 sometimes merely a small projection (pi. 9, fig. 215) ; maxilla III has 2 

 well-defined teeth on either side, and maxilla IV has a single tooth on 

 each side. 



Collection 1232-41 contains 2 gravid, egg-laden individuals; in these 

 the first 30 segments and the last 20 to 30 segments lack gonadial prod- 

 ucts, but a long intermediate region is closely packed with reddish or 

 salmon-colored eggs. The latter are nearly spherical (save for distortion 

 due to crowding) and measure about 0.22 mm across. 



Distribution. — L. latreilli is known from widely scattered areas, and 

 may be considered cosmopolitan. It has remained almost unreported from 

 the Western Hemisphere; Monro (1933, p. 84) reported it from Gor- 

 gona Island and the Galapagos Islands. L. nasuta Verrill (1900) from 

 Bermuda may be the same. Since the species has turned up so frequently 

 in the collections, it appears to be a very common species in the eastern 

 Pacific, chiefly below the intertidal zones. The present records extend 

 the range from central California, south to Peru, west to the Galapagos 

 Islands, and in the Gulf of Mexico to Colombia and Panama. Its bathy- 

 metric range includes intertidal to 275 fms (based on these collections).

This subspecies has sometimes been regarded identical with L. latreilli 

 Audouin and Edwards (above) (Fauvel, 1923, p. 431). The former is 

 here retained as a distinct subspecies to include a group of individuals 

 in which acicula are black; in the stem species they are yellow. Among
