This scarce species is represented in the collection by 9 speci- 

 mens of various ages, which are particularly interesting in that 

 they show the manner in which the dark pigment pattern, which 

 is such a characteristic feature of this and of most other species 

 of Lysiosquilla, is developed. 



In young specimens, 28 to 32 millimeters in length, there is 

 far less pigment than in adults, that on the exposed thoracic 

 somites being limited to a median patch with a blotch on either 

 side, while on each of the first 5 abdominal somites there are 2 

 short transverse streaks in the middle and 4 or 5 isolated patches 

 and streaks on either side. On the sixth somite there is a 

 somewhat indefinite transverse patch on either side and on the 

 telson a patch involving the bases of the 2 outer spines of the 

 dorsal series and the lateral marginal teeth (Plate I, fig. 2). 



At a later stage, in specimens 40 and 42 millimeters in 

 length, the various patches have almost completely joined, the 

 narrow anterior transverse band of the abdominal somites be- 

 ing, however, distinctly separated from the broader posterior 

 band (Plate I, fig. 3). 



The coloring of the adults differs but slightly from that of the 

 type specimen described by Wood-Mason. The amount of pig- 

 mentation on the rostrum is decidedly variable, and as a rule, 

 there is in the anterior two thirds of the carapace only a single 

 large indefinite pigmented patch which does not extend to the 

 lateral margins; it is rarely possible to distinguish 2 separate 

 transverse bands in this region. There is always a very heavy 

 transverse border to the posterior margin of the carapace. 



On the exposed thoracic somites, in place of the 2 bands found 

 in the type specimen, there is, in adults, only a single band 

 placed posteriorly. Double transverse bands occur on each of 

 the first 5 abdominal somites, the 2 bands being connected mid- 

 dorsally by a suffusion of pigment. 



The telson, the coloration of which could not be distinctly 

 made out in the type specimen, exhibits dorsally a single large, 

 semicii'cular, dark patch extending posteriorly to the base of 

 the marginal teeth and denticles, but in the middle of its distal
