1485. Pseudapocryptes punctularum (De Vis). South Seas (probably Banks Group). 

 Gdbiosoma punctitlarum De Vis, Proc. Linn. Soc. N. S. W. 1884, 449. 



This species, and the closely allied Gobiosoma guttulatum Macleay from Australia, said to be 

 scaleless, must be based on specimens of Pseudapocryptes, in which the minute scales have been 

 overlooked. They have no affinity with Gobiosoma. 



MARS Jordan & Seale, new genus. 



Mars Jordan & Seale, new genus of Gobiidre (strigilliceps). 

 This genus, typified by Mars strigilliceps, has the appearance of an ordinary goby with small scales, 

 as in Cryptocentrus, which it much resembles. On the vomer, however, are 2 or 3 large blunt teeth, 

 and the head is provided with minute filaments and pores arranged in straight lines and running in 

 various directions, somewhat as in Quisquilius and in Drombus. The canals on the planet Mars perhaps 

 justify the name of this genus. 



1486. Mars strigilliceps Jordan & Seale, new species. Samoa. 



Head 3.2 in length; depth 5; eye 4 in head; snout 5 in head; dorsal vi, 11; anal i, 9; scales 65, 

 counting from posterior margin of opercle. 



Body elongate, conipressed, the anterior profile rounded; jaws equal; mouth rather large, the 

 angle below middle of eye; several rows of small, sharp-pointed teeth in jaws; rather large blunt

teeth on palatines and vomer, no teeth on tongue; opercle and preopercle entire; head without scales: 

 a number of fine distinct raised chain-like lines radiating from eye and extending over or across the 

 cheek; one across the nuchal region, joined by 3 or 4 other similar lines which run longitudinally on 

 nuchal region; these probably serve as a mucus system; caudal peduncle 2.75 in head; second spine 

 of soft dorsal elongate, filiform, about equal to length of head; base of soft dorsal 1.25 in head, its 

 longest ray 1.75 in head; anal similar to soft dorsal, but with base and the anterior rays slightly 

 shorter; pectorals 1.1 in head, the tips under origin of soft dorsal; ventrals united, rather elongate, 1.25 

 in head, a distinct shallow membranous cup at base, the membrane entire; caudal rounded, about 

 1.25 in head. 



Life colors, dark olive with 4 narrow grayish cross-bands, rather obscure; front of head dusky; 

 lower part of head bronze-olive, with 6 sharply defined irregular white cross-bands; similar fainter 

 cross-bands on belly; the white bar from front of spinous dorsal crossing base of pectoral and 

 forming a ring about body; base of pectorals with white marblings; fins dusky olive with no clear 

 markings; scales small; head with numerous lines of small pores each with a minute filament. 



Color in spirits gray, with slight bluish wash; about 4 indistinct dusky blotches along side, the 

 blotch on side of caudal peduncle being most distinct; 5 distinct bands of black alternating with 

 bluish white surrounding the under part of head and throat, the posterior band white and extending
