The .scarcely differ from Giesbrecht's description. No glandular pores were obser\-ed in the natatory limbs. The labnaii proper, which suddenly raised froni the region hing in front of it, is by a transverse groove divided into an anterior and a more posterior portion; the latter is divided into three hairy lobes, a median and two lateral ones =" <= (text-fig. 9 a). The oral surface (fig. 5 a) shows a structure similar to that found in R/iiinalaj/us. but the two first groups of the longitudinal series consist of fairh- long and /-' , slender bristles. In front of as well as behind the transverse bar the skin is beset with a dense grotip of strong granules. In front of the trebly divided laiiiiiia labialis (fig. 5 b) a median longitudinal row of long and a lateral one of ver)- delicate setae are obserx'ed; in the middle a row of very short hairs is found on each side, single behind and double in front. Between the serrulae 6-dentatae a longi- tudinal lateral series, a median group and more posteriori)- a transverse group of short setae are found; behind the serrula an oblique group was seen. The area labialis possesses a central group of hairs between the labial lobes, partly continued on the latter, which bear four fairlj- regular rows of Text-fig. 9. Encalanns chngatiis Dana. a.
