from the summits of the median telson ridges, but Nobili has noted that they may 
cover the entire surface as is usually the case with the var. spinosus. It will be noticed 
that the median ridge of the telson is sometimes very much broader than the others, 
and this is the case with the type specimen figured by Henderson. 
Spirit specimens do not show any very characteristic colouring. Most of the 
examples are yellowish brown with a speckling of black chromatophores, which tend to 
form a transverse band in the posterior third of the carapace, lateral patches on the 
sixth thoracic somite, and a pair of ill-defined spots in the middle of the sixth thoracic 
and first abdominal somites. 
G. demani is a small species and does not seem to exceed 40 mm. in length. The 
specimens in the Indian Museum are not numerous :—

Gonodactylus demani has been recorded from Pulo Edam on the Java Coast (de 
Man), from Rameswaram in the G. of Manaar {Henderson) from the Persian Gulf and 
Red Sea (Nobili) and from Zanzibar (I,enz, Borradaile).

The telson is as long as broad, and the incision between the submedian marginal 
spines is slightly deeper than in typical G. demani. ‘The intermediate teeth of the telson 
edge are very small, and the laterals are minute or wholly absent. The dorsal surface 
is closely covered with small spinules, but in some cases the summit of the median ridge 
is bare. 
The claims of this form to varietal recognition are very slight and appear to rest 
almost solely on the greater length of the telson, and the reduced size of theintermediate 
' T am indebted to Mr. Patience for the opportunity of examining these specimens.
