The single ¢ specimen agrees in every respect with the figures given 
by Sars for I. spinicornis Boeck (l.c. p. 40, pl. 15) and by Della Valle 
for I. taurus Costa (Le. p. 801, pl. 3, fig. 1, pl. 27, figs. 1-22) except 
in the following points: the cutting-edge of mandibles is straight and 
has a small tooth at each end; the palp of Ist maxilla widens distally 
and has 6 little projecting teeth ; 2nd joint of 38rd peraeopod resembles 
that figured by Waiker for I. servicrus ; apices of telson project a little 
beyond the stout spine at the end of outer margin and bear in addition 
a minute seta set in a small indent ; accessory flagellum has 7 joints. 
The finger of gnathopod | expanded and spinose as in I tawrus. 
There seems little doubt that I. tawrus and spinicornis are con- 
specific. The discovery of the northern form spinicornis in the Java 
Sea is confirmatory. Sars’ figures of the 2nd joint of the 3rd peraeo- 
pod give the impression of being intermediate between that of tawrus 
and that of serricrus.
