females, some bearing eggs. The length of the carapace varied 

 from 12 to 20 mm., and there was no correspondence between the 

 size of the individuals aud the number of joints in their antennae. 



No two of the abnormal antennae were exactly alike. Thanks 

 to the excellent diagnoses given by de Man (joe. cit.) for the 

 festudinarhis-growp of Remljijes, I have been able to satisfy myself 

 that all tlie above specimens, including the first-mentioned with 

 three-jointed flagella on both the second antennae, were true 

 R. pacificus. 



On Plate XXXVI. fig. 3 a represents a normal second antenna 

 in this species ; figs. 3 h-i show the abnormal specimens in the 

 order in which I have alluded to them. 



Twenty-nine males and eleven females from Funafuti ; eighteen 

 males and fifty-eight females from iiotiima.

3. Report on the Gephyrean Worms collected by INIr. J. 

 Stanley Gardiner at E-otuma and Funafuti. By Arthur

(Plate XXXVII.) 



The Gephyrea collected by Mr. J. Stanley Gardiner dui-ing his 

 visits to E-otuma and Funafuti in the years 1896-97 comprise 

 specimens of two species of the Echiuroidea and twelve of the 

 Sipunculoidea. Of the latter, two species of ISijmnculus are iu my 

 opinion new, whilst a third, Physcosoma ^ varians Kef., is, so far as 

 I know, recorded for the first time from the Pacific. 



In nearly all the cases where species are common to the two 

 localities, the specimens from Funafuti were considerably smaller 

 than those from Eotuma. 



' The reason for adopting the generic name Phi/scosoma in place of Phymosoma 

 {Phymosomum Quatrefages) is given by Selenka in the Zool. Anz. Band xx. 

 No. .f)46, 1897, p. 460.
