, but there are some important features of the anterior setae that need documenting. Endite 1 anterior seta is the longest of all 10 setae and is smooth. Endite 2 main anterior seta is half the length of anterior seta 1, has a pecten of spinules and is attended basally by a very short spiniform seta. Endite 3s two anterior setae are like those of endite 2, but about 50% longer. Endites 4 and 5 have two anterior setae each, a longer one subequal in length to the main anterior seta of endite 2, with a pectin of spinules and a basal array of spinules. The shorter seta is about a quarter the length of the longer seta and naked. Endite 6 has just one anterior seta which is similar to the longer one of endites 4 and 5. The structure of these last five setae is unique to this species and serves to differentiate it from its sibling species described below.

noted a pair of stout spine-like outgrowths dorsally and two tumidities on the first genital segment, which Geddes (1891) reported also. The present specimens from Lake Ondit have a similar pair of spines but just one lateral tumidity and the Avon Lake specimens have a much larger pair of dorsal outgrowths directed posteriorly and terminating in a spine, but no apparent tumidities. It would seem then there is some variability in the expression of these outgrowths; this is accepted as normal for tumidites, given their variation, often associated with preservation, in
