Bdinoiuisoii — Stoiiiatopoda in tJic Bishof^ Miisniin 301 



For a ver\- complete discussion of this \vi(lel\- (listril)iitecl 

 species and its varieties the above reference may l)e consulted. 

 Attention is also called to Kem]Vs treatment of this species.^' 



Lanchester recognizes numerous varieties iiicluding those 

 considered as distinct by previous investigators and points out the 

 presence of intermediate forms that obliterate the structural distinc- 

 tions heretofore regarded as specihc. 



Two female specimens arc in the collection of the Bishop 

 Museum, both of whicli may be assigned to the above variety. 



The specimen from Guam corresponds in all details of the 

 telson with Lanchester's var. aciitus. The three carinae of the 

 telson are sharply defined, the median one descending abruptly 

 at its distal extremity. No appearance of lateral marginal teeth 

 is evident. The specimen from the Marquesas may be considered 

 an intermediate form between var. finnidiis Lanchester and var. 

 (iciifiis, although it more closely approaches the latter. As to 

 the carinae of the telson it closely resembles the latter variety, 

 but traces of lateral marginal teeth are to be observed in the 

 Marquesan specimen. 



The color of the Bishop Museum specimen from Guam, 

 preserved in alcohol, is yellowish in color with faint evidence 

 of greenish mottlings. The lateral borders of the carapace, the 

 posterior margins of the exposed thoracic and the abdominal 

 segments as well as the summits of the carinae are green. The 

 posterior edge of the sixth abdominal segment on the ventral 

 surface is distinctly marked by the same color. The dactylus of 

 the raptorial limb is greenish-white. A pink band marks the 

 outer surface of the manus near its distal extremity. The alco- 

 holic specimen from the Marquesas is greenish-brown above, with 

 the sixth alodominal segment and the telson considerably lighter 

 in color. The raptorial limbs are almost white. Lanchester's 

 specimen is recorded as "variegated green and white." 



The largest of the Bishop Museum specimens, the one from 

 Guam, measures 80 mm. from the tip of the medial rostral spine
