5. An Account or FISHES DISCOVERED OR OBSERVED IN Ma- 
DEIRA SINCE THE YEAR 1842*. By THE Rev. R. T. Lows, 
M.A 
Family ZEn1pz, 
1. Zeus concuirer. Lilacino-cinereus, capite inermi ; thorace 
pinnaque dorsali analique utrinque scutatis ; spinis dorsalibus 
anterioribus brevissime filamentosis ; pinnis ventralibus 1+ 5- 
radiatis ; caudali lunata. 
D. 9 v. 104-25 v. 26; A.2+(14+25 v. 26); P.13; V.45; 
_L+L+V: | MB. 7; Vertebree, 13 abd. + 21 cand. = 34. 
1+1.4VI. 
An example of this very fine new Dory was communicated, with a 
short notice, to the Zoological Society in 1845+. The row of large 
and remarkable naked bony scutellee on each side, at the base of the 
dorsal and anal fins, and along the breast or ventral line, afford a very 
striking character. They resemble the depressed shells of a Fvssu- 
rella seen in profile, and are beautifully radiato-striate, with a bright 
iridescent rose or lilac lustre, like the inside of a Trigonia. The 
umbo forms a smooth short strong spine or recurved prickle. The 
dark thumb-mark on the middle of the sides is present, as in Z. Gal- 
lus, L. Three examples only have occurred, measuring from eighteen 
inches to a little more than two feet in length. 
The supposed affinity between Zeus and Oreosoma, Cuv.f, is much 
corroborated by this fish. 
2. Arcyropeticus Ourersi. (Sternoptyx Olfersii, Cuv. R. 
An. (2nd edit.) ii. 316. t. 13. f. 2.) 
A single example, caught with a boatscoop on the surface of the 
water in the Bay of Funchal, June 6, 1845. 
The name of Pleurothysis, proposed in the ‘Fishes of Madeira,’ 
p. 64, for this portion of the Cuvierian genus Sternoptyz, has been 
anticipated by that of Argyropelicus, previously assigned to a Medi- 
terranean species by the Italian naturalist Cocco, and adopted in the 
‘Fauna Italica’ by the Prince of Canino. 
I have now succeeded in obtaining both the Cuvierian species of 
Sternoptyz in this part of the Atlantic ; though St. diaphana (Le St. 
d’ Herman, Cuv.) cannot, like 4rg. Olfersii, be perhaps fairly claimed 
at present to belong to the Madeiran fauna §. ° 
The Atlantic and Mediterranean species.of Argyropelicus may be 
thus distinguished : << 
Are. Ourersi1, Cuv pore altiore, altitudine dimidium lon- 
gitudinis (dempta pinna caudali) superante; parte postica 
(caudali) abbreviata ; capite duplo altiore quam longo; sterno
