Habitat. — Jaluit, Marshall Islands; January 13, 1900; shore ; six specimens, 
34,39. [H. 104-109.] 
These specimens present resemblances both to S. lunulata and S. mauritiana. 
The former of these presents in the figures given by Quoy & Gaimard a series 
of dark circular spots on each fin, and in three of the specimens taken by the 
* Albatross” similar spots, though not so regular either in form or distribu- 
tion, are found. On the other three they cannot be made out. The six speci- 
mens, nevertheless, seem to me all referable to one species, and I can only 
conclude that this must vary a good deal in the matter of coloration, as indeed 
is expressly stated by Quoy & Gaimard ; for in the case of S. guineensis, which 
is regarded, and no doubt rightly, by d'Orbigny, as being the same speeies, the 
Spots were not noticed until after it had been preserved. 
Turning to other characters, the horny rings of the suckers in the arms and 
tentacles resemble very clearly the figures given by d'Orbigny of S. lunulata, 
though the teeth are rather fewer than in that species and much less numerous 
than in S. mauritiana. On the other hand as regards the fin, the breadth is 
17 per cent of the length in S. lunulata, 15 per cent in 8. mauritiana, and 12.5 
per cent in the ** Albatross ” examples. 
To sum up, then, in the suckers the present form resembles $. lunulata, in 
the fin it is more like S. mauritiana, whilst in the coloration half the speci- 
mens show a very distinct, likeness to S. lunulata, whilst the others might be 
S. mauritiana. On the whole I have thought it best to refer these examples 
with some doubt to S. lunulata. It is, however, possible that S. lunulata and 
S. mauritiana may be only varieties of one widely distributed species. 
The tip of the tentacle shows the little spoon-shaped group of suckers to 
which attention was first called by Goodrich (96, p. 6).
