Habitat. — Both coasts of tropical America north to Florida and Gulf of California, 
south to Brazil. 
Etymology. — Outtatus, spotted. 
We have adopted the specific name guttatus for this species, because we feel sure 
that it is the real type of the Linnaeau Perea guttuta. In the paper of Jordan and Swain 
it is supposed that the Cugupuguacu of Willoughby may be the Bodianm erventatus, 
and that the latter species is concerned with Epinephelus ca,tus in forming the Liunaean 
type. We have since examined Willoughby’s work. His description is a copy of 
Maregrave’s, and his figure represents the Promicrops which is the subject of Marc- 
grave’s description, and nothing else. 
Linnaeus’s Perea guttata based, then, on Maregrave’s fish, and on the reprints of 
Maregrave’s description given by Willoughby, Ray, and Sloane, and on the Hind of 
Oatesby {Epinephelus catus), which both Catesby and Linnaeus wrongly supposed to be 
Maregrave’s species. The name gtittatus can not go with the Bodianus, because that 
species was not known to any of the writers before Linnaeus. It must go with 
Maregrave’s Cugupuguacu, which is the base of all the pre-Liunaean descriptions except 
that of Catesby. From Catesby’s figure Linnaeus must have taken the phrase in his 
diagnosis “ corpore punctis sanguineis adsperso.” Otherwise the Perea guttata rests 
entirely on Maregrave’s “ Cugupuguacu,” which is unquestionably our Promicrops. 
The three species of which the synonymy has been thus entangled should, in our 
opinion, stand as Epinephelus catus, Promicrops guttatus, and Bodianus cruentatus. 
Specimens of this huge Serranoid are in the Museum at Cambridge from Rio de 
Janeiro, Bahia, Pernambuco, and Cannarivieras.

A few changes are made in the arrangement of the species of this genus as given 
by Jordan and Swain. Three species, M. olfax, M. calliura, and M. dimidiata, have 
been examined by us, and can be more correctly defined than was possible when the 
former paper was written. Two new specie.^i, M. xenarcha and M, jordani, have been
