Nile Rosén 



Several specimens were collected among sponges, corals etc. near the shore 

 at Mastic Point, Andros. 



This new species is very distinctly marked from other species of this genus 

 by having 7 dorsal spines, and also through the dentition and coloration. 



Whether the genus Garmannia is a quite distinct genus, I am not sure. I 

 have had no opportunities examining any other specimens of this genus, neither 

 of the two Pacific genera Gymneleotris Bleeker and Pycnomma Rutter ^ These 

 three genera seem to agree with each other in the general shape of head and body, 

 in the head and anterior part of body being naked, and in the presence of curved 

 teeht in the jaws. The greatest difference between Gymneleotris and Pycnomma on 

 one side and Garmannia on the other seems, according the descriptions, to be that 

 the ventrals are united in the latter genus, separated in the two other. In Gar- 

 mannia rubra mihi the ventrals are united by a very thin membrane wliich can 

 split very easily. How far from each other the two ventrals are separated in 

 Gymneleotris and Pycnomma I do not know, but I have a slight suspicion that 

 the separation of the ventral fins may be due to a splitting of the thin membrane 

 uniting them, especially as the representatives of these genus are know only from 

 single specimens. In that ease I think these three genera ought to be united in 

 one. Perhaps, my suspicion is perfectly false, but that can only be decided by a 

 careful examination of all the forms in question. 



It seems to me impossible to maintain the distinctness of the two species E. 

 naucrates L. and E. naucrateoides Zuiew, based as it is on the number of the laminee 

 of the disk and the proportion between the length of the disk and the body. I 

 have collected several specimens at Mastic Point, of which I give below a few notes 

 about the named characters. I refer them all to E. naucrates L. being the earliest 

 described form.
