122 Memoirs of the Indian Museum. [Voi,. IV, 



The only male specimen examined is very small (48 mm.) and does not possess 

 any special structural modifications characteristic of its sex. 



The colouration of spirit specimens is very characteristic. The whole of the ros- 

 trum except the apical spine and a narrow proximal band is black. There are 

 three broad transverse bands of the same colour on the carapace, the posterior of which 

 encloses a pale oval spot on either side. The last three thoracic and all the abdominal 

 somites have each a broad, median, transverse, black band, leaving pale anterior 

 and posterior borders. On the sixth somite the posterior pale border is sometimes 

 obsolete. The telson has a pair of large rounded patches of the same black pig- 

 ment, involving both the intermediate and lateral dorsal spines and frequently coal- 

 escing anteriorly. In some specimens there is a single large patch which is cut into 

 four distal lobes. The inner uropod is entirely black, as are also the spines of the 

 bifurcate process except at the extreme apex. The peduncular segment is dark proxi- 

 mally ; the first segment of the exopod has a round black distal spot, while the 

 ultimate segment is obliquely divided into dark anterior and pale posterior portions.

Lysiosquilla acanthocarpus has been recorded from Port Essington, N. Australia 

 (Miers), from Penang (Miers) and from Trincomali (Müller, sub S. sarasinorum). 



Miers l has described a small female Lysiosquilla from Goree I., Senegambia, under 

 the name L. acanthocarpus var. septemspinosa. This specimen differs from typical 

 acanthocarpus in the slightly transverse rostrum, in the less prominent eyes and in the 

 possession of seven teeth on the dactylus of the raptorial claw, the penultimate of which 

 is not shorter than the antepenultimate. This form should, perhaps, be recognized as 

 a separate species.

 This species is very closely allied to the preceding, differing from it only in the 

 following particulars : —
