90 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 25 



Interramal pouches, resembling those in species of Laonice, are 

 present in mature individuals; they occur first on the last several 

 branchial segments and attain their greatest development in the goniadal, 

 or postbranchial segments. 



Hooded hooks are first present in neuropodia from about the thirtieth, 

 or last branchial segment ; they are accompanied by long, pointed setae 

 at the upper end of the fascicle, and the hooks are mainly in the lower- 

 most part of the series. Seen individually, the hooks are distally hooded, 

 have a main fang nearly at right angles to the shaft, and a small distal 

 tooth, best seen when the hook is on its side (PI. 11, fig. 3). Notopodia 

 throughout have only long, slender, distally pointed setae. 



Spio punctata shows resemblance to Spio multioculata (Rioja) (see 

 Fauvel, 1927, p. 44) ; in the latter, however, the hooded hooks are 

 distally obtuse, are first present in an earlier segment, and some of the 

 anterior neuropodia have curved acicular spines. 



Spio punctata is best represented in samples taken in the vicinity of 

 Santa Catalina Island, in depths of about 40 fms. It is associated with 

 other invertebrate animals including Amphiodia urtica (Lyman) (ophiu- 

 roid), Leptosynapta albicans Selenko (holothuroid), polychaete species: 

 Artacamella hancocki Hartman, Glycera americana Leidy, Lu/nbrineris 

 calif or niensis Hartman, Nephtys ferruginea Hartman, Sternaspis fossor 

 Stimpson, Sthenelanella uniformis Moore, Tharyx tesselata Hartman, 

 Pholo'e glabra Hartman, and others.

This is a much smaller form than the stem species, individuals meas- 

 uring less than 50 mm long. The prostomium is truncate in front and 

 acutely pointed at its median position. A caruncle extends posteriorly 

 from the main part of the prostomium, between the palpal bases, where 

 there is a short median antenna. Branchiae are present from the second 

 setigerous segment and continue posteriorly through most of the length 

 of the body. They are fused with the postsetal lobe and have a short 

 free tip.
