CBUSTACEA OF FEAKZ-JOSEF LAND. 63 



MALACOSTEACA. 



MACRUEA. 

 (Tribe Caridea.) 



Genus Spirontocaeis, Spence Bate, 1888. 



Spirontocabis gtaimardii (Milne-Edwards). (PI. 3. figs. 1, 2.) 

 1837. Hippohjte Oaimardii, Milne-Edwards (26), p. 378. 

 The Bruce collection contained a single adult female with ova ; 

 it was taken about two-thirds of a mile south-west of Elmwood, 

 in 18 fathoms water, on June 7th, 1897. The length of this 

 specimen was about 62 millim. ; the armature of the rostrum 

 consisted of seven teeth on the upper, and five on the lower edge, 

 as shown in the figure (fig. 1). 



(?) SpiRONTOCARis Phippsii {Kroyer). (Pi. 3. figs. 3, 4.) 



1841. Hippolyte Phippsii, Kroyer (42), p. 575. 



A single specimen of this species was dredged in 8 fathoms, 

 off "West Bay, Cape Plora, on July 24th, 1897. Kroyer states 

 that in this species there are four teeth on the front part of the 

 lower margin of the rostrum, but in this specimen there are seven 

 teeth ; the first three (counting from the apex of the rostrum) are 

 each somewhat stouter than the next four and are moderately 

 wide apart, the fourth, fifth, and sixth are close together, 

 while between the sixth and seventh there is an interval about 

 equal to that between the third and fourth as shown by the 

 drawing (fig. 3). But though the Cape Plora specimen differs 

 from the typical S. phippsii in this respect, it seems to agree 

 with it otherwise ; variation in the number of the teeth of the 

 rostrum amongst the group of crustaceans to which this one 

 belongs is not uncommon. 



Spirontocaris POLARIS {Sabine). 



1824. Alpheus polaris, Sabine (65), p. 238, pi. 2. figs. 5-8. 



There were several specimens of this species in the Bruce 

 collection, some of them being females with ova. Considerable 

 variation was observed in the number of teeth on the upper and 

 lower margins of the rostrum ; on the upper margin the number 

 varied from four to seven, and on the lower margin from one to 

 three. All the specimens were taken in the vicinity of Elmwood 

 at the western extremity of Northbrook Island, and mostly
