are so extremely bad, so incomplete and incorrect that, imfortunately, the classificatory 

 position of these specimens cannot be decided from this work either. It is, however, to be 

 noted that the drawing of the shell given by this author shows a type that approaches con- 

 siderably more the one which is characteristic of my above described species. The exopodite 

 of the second antenna appears to be without basal spines; p. 108. 



Without giving any detailed information about the type or the species, J. RICHARD 

 mentions (1900, p. 83) that a Gigantocypris 1 cm. long was caught at a depth of 1732 metres 

 off the Azores, thus in the neighbourhood of stations 51, 53 and 62 of S/S „M i c h a e 1 

 S a r s". — In this author's work of 1904 a specimen of this genus is also mentioned from 

 Atlantic (p. 15). 



G. H. Fowler mentions that two specimens of this genus were caught by S/S „R e- 

 search" in 1900 in the Bay of Biscay (1909, p. 257). There are no detailed descriptions. 

 „By size they belonged to MOller's species pdlucida; the perfect specimen measured about 

 13 mm." 



Similarly G. Agassizi is mentioned in C4. \V. MULLER's work of 1908, p. 87; no figures 

 or descriptions are given. 



Whether these finds are to be referred to G. Mulleri it is impossible at present to decide 

 with absolute certainty. As is seen above I have written FowLER's form as synonymous to 

 this species, although it seemed to me best to add a query. 



There can of course scarcely be any doubt that the species Gigantocypris pellucida de- 

 scribed by Th. Scott, 1912b, p. 5 from lat. 58« 43' N., long. 9» 6' W. — thus in the neighbourhood 

 of S/S ,,M ichael Sar s's" stations nos. 98 and 101 — is identical with G. Mulleri. Small 

 differences are to be noted in some characters; for these I need only refer to Til. ScOTT's and 

 my figures. The explanation of these differences lies probably, however, chiefly in lack of 

 accuracy on the part of Th. Scott. 



All the larvae investigated by me were females, in either the last or the penultimate Larvae. 



larval stage; the number of furcal claws was nine or ten. 



This form is named after G. W. MUller, who is incomparably our greatest expert on the ^ "'""■ 



Ostracod group and the investigator through whom the first representative of this genus, .so 

 peculiar in its habitus, was made known to science.
