Arctus martensi Ortmann, Zool. Jahrb., Syst., VI, 1891, 44; X, 1897, 272. 
Distribution. — South coast of Molokai Island, 43 to 66 fathoms, station 3850; Auau Channel, 43 to 32 
fathoms, station 3872; vicinity of Kauai Island, 230 to 53 fathoms, station 4002; Japan (de Haan); 
Kagoshima (Ortmann). 
In the Philadelphia Academy of Natural Sciences is the abdomen 80 mm. long of a dried specimen 
of Scyllarus, labeled “Sandwich Islands, T. Nuttall.” This is not mentioned in Randall’s list (1840). 
It has the size and sculpture of the European S. arctus ( L. ), and the locality label is probably an error. 
Scyllarides squammosus (Milne Edwards). 
Scyllarus squammosus Milne Edwards, Hist. Nat. Crust., II, 284, 1837. Mauritius. 
Scillarus latus Randall, Jour. Acad. Nat. Sci. Phila., VIII, 1839 (1840), 137. Not Scyllarus latus 
Latreille, 1803. 
Scyllarus sieboldi de Haan, Fauna Japon., 152, pi. xxxvi and xxxvii, fig. 1, 1841. Nagasaki. 
Scyllarus haanii de Siebold, MS., de Haan, Fauna Japon., 152, pi. xxxvm,- fig. 1, 1841. 
Scyllarus luridus Stimpson, MS. label in Museum of Comparative Zoology. 
The Hawaiian specimens resemble most nearly de Haan’s figure of S. sieboldi; S. haanii has the 
elevations of the surface more prominent, and is probably only a variety. 
Honolulu; Honolulu market; Honolulu Reef, Dr. W. H. Jones; northeast coast of Hawaii, 29 to 
26 fathoms, station 4053.
