G. hamatus and 0. macropus without contrasting them in any 

 way, and, indeed, the parts he described in the one species he 

 altogether passed over in his description of the other, and vice 

 versa. Such descriptions as are given by this author are so 

 obviously inexact, and -his figures without explanations so 

 unintelligible, that the whole can only be ignored. Nos. 1 and 2 

 are therefore struck oif the above-given list. 



This circumstantial evidence for the identity of the above- 

 named species with that of European seas has been completed by 

 my examination of a specimen, undoubtedly of the latter species, 

 fi'om the Cape of Good Hope. I owe this opportunity to the 

 kindness of Prof. Mcintosh. 



Grube's description of C. cq^pendiculattts is exceedingly short 

 and without figures. The differences from C. variopedatus ai-e 

 (1) only 8 parapodia in the first body-region ; (2) the uncini of 

 the tori of the first body-region " are armed with about 20 very 

 short denticles." As Joyeux-Lafluie shows, C. variopedatus 

 sometimes has only 8 parapodia in the anterior region, and 

 " about twenty " teeth to the uncinus is too slender a distinction 

 for the creation of a new species. Whether or no C. appendi- 

 cidatus is a synonym of C. variopedatus cannot at pi-esent be 

 stated. 



We conclude, therefore, that the genus Cluetopterus as at 

 present known contains four species, including the two new 

 species from Gardiner's collection, distributed as follows : — 



1. C. variopedatus. European seas, the Straits of Magellan, 



the Antilles, North-American coasts. Cape of Good Hope. 



2. C. cautus. South of Japan. 



3. C. lonqimanus. 1 mi -a/r i t v i • i

4. 6. longipes. J ^ ° 



In addition are many species partially described, which may 

 or may not be identical with C. variopedatus or may be as yet 

 xmknown species. The former is the more likely explanation, 

 and in that ca.se C. variopedatus has been recorded from almost 

 the whole of the Northern and Southern hemispheres. 



Ch^topterus longimanus, sp. n. (Plate XYIII, figs. 1, 2.) 



With eleven '■^thoracic''' parapodia, of which the \st is longer 

 than the 2nd and 11th and nearly as long as the longest, the 

 9th. Hind hody short, of abotit timnty segments. The selce. of 

 the notopodia of this region have flexible ends. Uncini large, dark 

 brown in colour, loith few teeth. 



Otherwise the species resembles C. variopedatus. 



Locality. Suvadiva Atoll, the Maldive Archipelago, 30 fathoms. 

 Rough stony bottom. 



The single specimen is a male, sperm-morulse rendering the 

 hind body and its parapodia an opaque white. It is therefore 

 probably near to its full size, though its total length is but 

 76 mm. The length is made up thus : A, 15 mm. ; B, 24 mm. ;
