NO. 1 HARTMAN : POLYCHAETOUS ANNELIDS 93 



III has 8 teeth, and V has a single tooth. In plate II (on either side) the 

 teeth are all about equally large and approximately equidistant from one 

 another. The carriers are longer than broad (pi. 11, fig. 251). 



Setal structures agree reasonably well with similar ones in the stem 

 species. Anterior hooded hooks are clearly tridentate, the distal tooth is 

 the largest (pi. 11, figs. 249, 250). A second parapodium has 4 hooks, 

 with a few very slender, pointed setae. By the eighth setiger the hooks 

 are replaced by composite spinigers. Parapodia are supported by 2 yellow, 

 pointed acicula. A twelfth parapodium has 2 embedded acicula; below 

 there are 4 composite spinigers, above there are 4 longer, simple, bilim- 

 bate setae, and medially there are about 8 similar though shorter setae. 

 Pectinate setae are few in number, about 3 to 5 in a parapodium where 

 present, and have 7 to 10 fine teeth at the distal end. 



The type collection (1048-40) includes a thin, parchmentlike tube, 

 covered over closely with small sand and shell particles, and appearing 

 finely granular to the unaided eye. 



A^. stigmatis cirrata differs from the stem species largely in having 

 greatly prolonged cirri and postsetal lobes, especially in anterior segments. 

 Ventral cirri are cirriform through 6, not 3, setigers.

A single collection of 6 tiny, not quite complete specimens includes 

 individuals which depart so widely from others of this group that they 

 cannot be referred to any of the others. They are obviously adults, as 

 evidenced by the ovigerous region in some individuals. In size they com- 

 pare favorably with one another; one piece with 83 segments measures 

 19 mm long, it is incomplete posteriorly; another of nearly 90 segments 

 measures 24 mm long, but a short posterior end is missing. All are slen- 

 der, filamentous, hardly a millimeter across. They are drab, without 

 color markings, but perhaps faded. There is nothing unique about their 

 appearance save that they are mature individuals in spite of their small 

 size.
