It is difficult to diagnose the species mentioned by 

 Sclimarda from Chili, as the figures and descriptions of the 

 feet are too indefinite. In his first species, Glycera micro- 

 gnatha, he describes the branchia on the foot as terminal, 

 but whether the description applies to the terminal papilla of 

 the foot or a branchia is doubtful. The dorsal cirrus is also 

 situated above the foot. In G. macrorhiza the terminal 

 papilla of the foot appears to be his branchia, and the dorsal 

 cirrus is neither shown in the figure nor referred to in the 

 text ; yet the form of the foot closely approaches that in the 

 Japanese species. Glycera monodon, Schmarda, again has 

 only a single tooth (?), the same kind of branchia (the 

 terminal papilla), and a short ventral and a dorsal cirrus. 

 The form of the tooth approaches that of the Japanese 

 example. His G. diodon is described as having no branchise, 

 two processes to the teeth, and conical, dorsal, and ventral 

 cirri. The setigerous lobe has a clavate papilla at the tip. 

 It is possible that all the foregoing species and the Hemipoda 

 patagonica of Kinberg may be identical with the Japanese 

 form, as Ehlers thinks, and all appear to belong to the genus 

 Hemipodus , De Quatrefages. 



Hemipodus simplex, Grube, var. 



Procured at Koba, Japan, lat. 34° 27' N., long. 156° 50' E., 

 by Capt. St. John, in 1874. 



Externally this form differs from Glycera in the somewhat 

 more elongate condition of the body, which appeared to be 

 about 3 or 4 inches in length, and by the wide spaces 

 between the feet. The latter, however, were closer ante- 

 riorly and posteriorly than they were in the middle of the 

 body. The head was absent, having been detached after 

 rupture by the proboscis. Posteriorly the body gradually 

 tapered to a tail, which ended in two short cirri. 



The first region of the proboscis was longitudinally 

 streaked. The teeth are rather short, with a single slightly 

 curved spur (PI. IV. fig. 4), which is situated near the basal 

 part or socket of the tooth. 



The papillie of the proboscis are simple and filiform 

 throughout (PI. IV. fig. 4), tapering gently from the base 

 to the tip, finely streaked longitudinally and with minute
