long, outermost obviously tapered aiul more 

 slender than other two. Branchial segments 

 8-6, all with notosetae hut without neurosetae. 

 Notosetae of segment 8 as long tapering ])aleae 

 ( Figure 15k) reaching tip of prostomiuni. Noto- 

 setae of segment 4 as minute winged capil- 

 laries, those of segments 5 and (5 longer but 

 still shorter than those of uncinigerous seg- 

 ments. Twelve uncinigerous thoracic segments 

 from segment 7. Notosetae (Figure 15h) as 

 bilimbate cajjillaries; notopodial lobes of pos- 

 terior thoracic segments with a jjair of small 

 cirriform projections (F'igure 15m). Thoracic 

 uncini (Figure 15i, j) with two rows of five teeth 

 above rostral point ami basal prow. Abdomen 

 of 13-14 segments bearing oval uncinigerous 

 pinnules without superior papillae. No vestigial 

 notopodia. Anal cirri not evident. Abdominal 

 uncini (Figure 151) with an irregular double 

 series of four teeth above rostral point. 



Remai'ks. — The genui^ SoDuitlnlht was erected 

 by Verrill (1873a) for S. eloiigata, which lacks 

 paleae, has 3 pairs of gills, 12 uncinigerous 

 thoracic segments, uncini with a single row of 

 teeth. As originally defined, Sann/tl/illa was 

 closely related to Eiisa))iytlia Mcintosh and 

 Eclysippe Eliason. SamytheUn was redefined by 

 Day (1964) to include all three genera and in 

 the emended definition paleae may be jjresent 

 or absent. The type species of Ecli/sippe is 

 Li/-^ippf ra)H'lli Fauvel, with paleae smaller 

 than the noto.setae of the uncinigerous thoracic 

 segments. Fauvel's description left it uncertain 

 whether there were thi-ee or four pairs of gills. 

 Elia.son's description of Eclysippc vcuicUi is 

 clear, and the species he examined is certainly 

 the same as the one described above from 

 Beaufort. I doubt, however, that it is the same 

 as Fauvel's Lysippe rcvwlli and, for this reason, 

 I have renamed it ScniiythcUa elias(nn.
