a vaiyiiig iiuxnber of very small teeth, which continue in a lateral row of about 8 

 small conic teeth. The tips of the incisiors and canines brown. The lateral 

 teeth white. 



The colour is dark red, disappearing in alcohol. Length about 2,5 cm. Very 

 common clinging to rocks along the shore at Mastic Point, Andros, after which 

 place I have named it. Found also at Nassau. 



This species is characterized especially by the dentition. It seems to show 

 most resemblance with the imperfectly known G. macropWialmus Güntek, the habitat 

 of which is not known (propably West Indies). There is some difference in den- 

 tition, but this may be due to an imperfect description of G. macropMlialmus. 

 Until further notices are not given about this species, the two species must be 

 regarded as distinct. 



Arhàciosa rupestris, Poet. Fig 3. 



Gohiesox rupestris, Poey, Memorias sobre la Historia natural de la isle de 

 Cuba Tom. 2. p. 283 (1856 — 58). ,0f this species, hitherto known only from Cuba, 

 several specimens were collected among pieces of rocks and corals along the shore 

 at Mastic Point, Andros. 



The largest specimen 27 mm. In Jordan and Evermann's description (pag. 2341) 

 a few words are omitted, which makes the description of the markings not correct. 

 It otaght to be «each side of the back with 6 large oval spots». Poey writes (pag. 

 284) »sur chaque côté du dos six grosses taches ovales». In upper jaw on each 

 side behind the incisors a few small teeth, not followed by other teeth. In lower 

 jaw on each side behind the 3-serrated incissoi's one large, curved canine, not 

 followed by other teeth.

I collected several specimens both at Nassau and at Mastic Point, which all 

 as far as I can see, must be referred to this species. They vary, however, rather 

 much as to the number of rays in dorsal and anal, as well as to the number of 

 filaments constituting the fringe above eye and that one on nape. The cross bands 

 are also variable in number. In some specimens they extend to the edges of anal 

 and dorsal, in some only to the basal parts of these fins. All specimens with a band 

 of teeth in jaws. As the descriptions hitherto given about L. nuchipinnis do not 

 state anything about such a great variation of the rays in dorsal and anal, I am 

 giving below a table showing the number of them in the specimens I have collect- 

 ed. Perhaps a future study of a greater number of specimens will show that 

 nuchipinnis includes several distinct forms.
