This species was accurately described by Grube, though he had only a single specimen 

 at his disposai; afterwards it was only met with by Fauvel among the Annelids of the Persian Gulf. 



The Siboga Expedition collected 4 complete and 4 incomplete specimens ; the largest 

 of them (Stat. 305) has a length of 24 mm. and consists of about 40 segments. The species 

 can be easily recognised by its conspicuously coloured elytra, that issuing from the scar of 

 attachment, are divided in four opposite areas, an exterior and interior one, dark, blackish, and 

 an anterior and posterior area, pale, buff-coloured. The large anterior, pale area is densely 

 beset with small tubercular papillae, which interiorly and posteriorly pass into large acute spines ; 

 moreover the interior and posterior margin is provided with a fringe of long, cylindrical j^a- 

 pillae, with dilated tip, that anteriorly decrease in number and in length. 



The dorsiim of the segments shows an elongated transverse area, acuminate at both 

 sides and bordered by a black and white line. Characteristical for the species is the semi- 

 lunar lobe at the posterior ventral margin of each segment, at the median side of the nephri- 

 dial papilla ; it commences on the 4"^ segment, but it does not cease on the 27'"^ one, as 

 stated by Grube. The dorsal fascicle, like in the preceding species, consists of a large tuft of 

 faintly bent bristles (PI. XVIII, fig. 2) with a single tip-, they are thicker than the ventral 

 ones, and surrounded over the greatest part of their length by densely crowded laciniate frin- 

 ges. The ventral bristles (PI. XVIII, fig. i) bear a fine pointed tooth below their tip, whereas 

 the subterminal dilated part is provided with the usual alternating denticulated rows. In the 

 dorsal part only of this fascicle there occur sonie slender bristles, with undivided tip, which over 

 more than half their length are provided with denticulated rows. 





Genus Allmaniella Alc. Intosh. 



Mc Intosh, Challenger reports, Zoology, Vol. XII, 1S85, p. 102, 



This genus differs from ]\xralepido}iotus especially by its large eyes and the long pro- 

 longations of its setigerous lobes.
