All the Euryt/ioc-spec'imens from the above-named localities in the Malay-Archipelago 

 appear to belong to Eurytho'è complanata (Pall.), with which E. alcyonia Sav. and E. pacifica 

 Kinb. must be considered to be identical, according to the recent investigations of Ehlers l ) and 

 Potts "). The species is characterized by the presence of a caruncle (PI. IX, fig. 20), commencing 

 on the middle of the syncipital region of the prostomium and extending till upon the third or 

 to the anterior part of the fourth segment; in E. óorea/is, according to Racovitza 3 ), the caruncle 

 only commences at the posterior border of the prostomium. The caruncle of E. complanata is 

 a rather narrow flexuous crest with 6 to 7 vertical folds along its lateral sides, situated like 

 the buttresses against a wall ; a horizontal plate, as present in Chloeia and Noiopygos, could not 

 be detected. The unpaired antenna, placed in front of the caruncle, is small, usually shorter than 

 the paired ones ; however in some specimens the difference is not very great. The mouth is 

 surrounded by the anterior four segments; however the wedge-shaped buccal segment lies thus 

 inclosed between the palpar region and the second segment, that it does not reach the margin 

 of the mouth, exactly as stated in my description of E. alcyonia in 1886 4 ). The anal opening 

 is an elongated oval fissure, extending over 6 or 7 posterior segments, that are very narrow 

 and densely crowded together; a rounded papilla is situated at its distal end. When Ehlers 

 (Florida-Annel. p. 30) says: "das letzte Segment tragt zwei knötchenförmige Aftercirren", this 

 must undoubtedly be considered as a slip of the pen. 



The neuropodial fascicle principally contains short, thick, bifurcated bristles ; in the 

 majority of the specimens I examined, they did not show any conspicuous serrations, at the most 

 one or two shallow denticles were visible. Therefore I cannot understand how Mc Intosh 5 ) 

 — on the authority of Grube — could identify his worms from Bermuda with the E. pacifica 

 of Kinberg, who in his diagnosis of this species 6 ) clearly states: "setae pedum ventralium 

 laeves", whereas those of E. corallina and E. chilensis are described and figured as sub- 

 serratae. Besides these short bristles there occur in the ventral fascicle some (usually one or 

 two) slender ones, that have the furcated part twice or thrice as long as that of the preceding; 

 their longest limb is finely serrated in its distal part, as already described and figured by 

 myself 25 years ago and afterwards confirmed by Beddard 7 ). Therefore I presume, that these 

 denticulations have been overlooked by Gravier 8 ), as may happen easily when the bristles are 

 not situated and drawn justly in profile. Also the faintly bifurcated setae of the dorsal fascicle,
