60 ME. C. TATE REGAN ON ■ [May 12, 



has presented the types of the new species and other desiderata 

 to the British Museum, whilst the greater part of the collection 

 has been sent to the Museum at Bei-ne. 



KAIIDiE, 



Raia cyclophora, sp. nov. 



Snout with an obtuse triangular projection of moderate length. 

 Anterior border of pectoral emarginate. Eye-diameter 3|-4 

 times in the distance from their anterior margin to the tip of 

 snout and equal to interorbital width. Mouth strongly curved, 

 36-38 rows of teeth in the upper jaw. Body smooth, except for 

 a series of 10-11 spines on the dorsal surface of the tail, and, in 

 the male, a double series of curved spines on each pectoral. 



Male with claspers extending to below first dorsal fin. 



Uniform brownish, with a conspicuous black circle on each 

 pectoral near the middle of its base. 



Description based on two examples from Rio Janeiro^a female, 

 480 mm. in total length, and a male, measuring 410 mm, 



MUR^NID^. 



MUR^XA HELENA Linn. 



Five specimens from Rio Janeiro are all dai-k brown in colour, 

 with numerous small white spots on the head, body, and fins. 

 Examples from the Mediterranean in the British Museum Collection 

 are similarly coloured, and it seems probable that 31. insularum 

 Jordan & Davis, from the Galapagos Is., which is said to difier 

 from AI. helena in having this system of coloration, in reality may 

 not be distinct. 



AlHERINIDiE. 



Athertnichthys brasiliensis Quoy & Gaim. 



Of two examples one has four dorsal spines, the other five. In 

 the original description it is stated that the lower jaw is shorter 

 than the upper, so that Messrs. Jordan and Evermann are 

 incorrect in referring this species to Chirostoma, which is dis- 

 tinguished by " the very long and strong mandible, which 

 protrudes beyond the upper jaw." The Atherinichthys brought 

 from Mexico by Salle and named A . bi-asiliensis by Dr. Giinther, 

 is a distinct but allied species, which I propose to name A. sallei*. 



* Atherinichthys sallei, sp. nov. :— Depth of body rather less than length of 

 head, 5 tnnes in total length. Snout much shorter than eye, the diameter of which 

 IS 2-1 tmies m length of head and equal to interorbital width or length of post- 

 orbital part of head. Lower jaw somewhat shorter than upper ; maxillary extending 

 to vertical from anterior margin of eye. Sc. 43/10. D. IV, I 8 ; A. II 19. Spinous 

 dorsal commencing above origin of anal; anterior rays of soft dorsal and anal 

 produced, longest anal rays equal to depth of body ; pectorals falcate, as long as head ; 

 origin ol ventrals equidistant from posterior opercular margin and first anal ray ; 

 caudal emarginate. A sharply defined silvery lateral band as broad as a scale, 

 description based on a single example, 75 mm. in total length, from Mexico. 



ihis species agrees in every respect with Messrs. Jordan and Evermann's definition 

 ot Menidia. It resembles A. hrasiliensis in the disposition of the fins and number of 

 raj's, but the latter species has a much longer head, longer snout, smaller eve, &c.. 

 and very indistinct lateral band.
