 the integument and situated some distance apart, immediately 

 behind the tentacles ; they are, however, often scarcely 

 discernible. Branchial pajnllce in five transverse rows, two 

 on each side; but in the adult generally three in each fascicu- 

 lus of the second row, and rarely three in the first. In the 

 form figured by Meyer and ]\Iobius there are throe papilUv in 

 first and second fasciculus and four in the tiiird ; but the 

 additional papilla? beyond the primary two are not one third

 pigment-cells of a blackish hue, which occasionally also cxtoml 

 over the papilla?. Length two tenths to three tenths of an 

 inch.
