STEBBING— ISOPOD A 101 



Locality. The single specimen, a male, was taken by Mr Crossland at Zanzibar in 

 1901. 



The specific name is given out of respect to Mr J. T. Rennie Reid, the Edinburgh 

 lithographer, who during the past five and twenty years or more has faithfully reproduced 

 on stone the majority of my drawings of Crustacea.

To this species I refer a specimen from Mauritius, which agrees in all essential 

 particulars with that which I have described and figured (loc. cit., p. 23, pi. 5 a) as the 

 female or a younger form. The two pairs of antennas and the shape of the telsonic 

 segment perfectly agree, and the great black eyes in like manner stretch all across the 

 head and fold under. But the size of the specimen is considerably smaller. Its greatest 

 breadth is at the fifth peraeon segment, with the two following segments shorter than 

 the others, the seventh being completely concealed in dorsal view and furnished with 

 a pair of legs devoid of spines and much smaller than the fourth perasopods. It is 

 interesting to notice that this youthful characteristic is retained in a specimen otherwise 

 so fully developed. But in the pleon also only four segments are conspicuous in advance 

 of the telsonic segment, instead of five as in the adults. 



Length 7*5 mm. Breadth at widest part 3 mm.

A single specimen, of the female sex, obtained by Mr Crossland in 1901 at Zanzibar, 

 measures 17 mm. in length by 8 mm. in breadth. There is a longitudinal dorsal depression 

 between the rather large dark eyes. The telsonic segment is well rounded distally.
