The single $ specimen agrees in every respect Avith the figures given 

 by Sars for I. spinicornis Boeck (I.e. p. 40, pi. 15) and by Delia Valle 

 for I. taurus Costa (I.e. p. 801, pi. 3, fig. 1, pi. 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 1st maxilla widens distally 

 and has 6 little projecting teeth ; 2nd joint of 3rd peraeopod resembles 

 that figured by Walker for I. serricrus ; 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 flagelluni has 7 joints. 

 The finger of gnathopod 1 expanded and spinose as in I taurus. 



There seems little doubt that I. taurus 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 taurus 

 and that of serricrus.
