 Of this remarkable species we liave 11 specimens from the coral reef at Apia, and 3 from Pago 

 Pago. The fish is not rare in the crevices of the coral reefs. It reaches a length of little more than 

 an inch, but all our specimens are less than an inch in length. 



The genus Parngohiodon is separated from Rhitwr/ohivs by the short plump body, the globular 

 liead, the presence of papilliB on the skin of the head, by the short, cup-shaped ventrals, and by the 

 short oblique mouth, with two small canines. The scales are large, the fins short, the first dorsal 

 with 6 spines, and the sides of the head are without scales. 



Life colors of a specimen from Pago Pago, all fins and body up to base of dorsal and pictnriil 

 black; in front of that smoky red or flesh color; finely rugose and punctate; ventrals fused In fniiij n 

 Heshy rugose and papillate pad. 



Another specimen from Apia was in life golden-yellcw, witli the tins all deep brownish black, 

 mouth very small, lips black, iris red, head more brownish. 



A third specimen from this locality differs in the yellow jiectciral and ventral, the pectoral lUisky 

 at tip. (This may be a female. ) .\ faint pale edge to anal, etc. ; vertical fins deep blue-black. 



1446. Paragobiodoii xanthosomus (Bleeker. ) Samoa.

.' Gohius mailei Garman, Bull. Mus. Comp. Zool., XXXIX, 1903, 234, pi. 3, fig. :;. Great Barrier Reef of Australia. 



Other specimens which we identify as Puragohiodon xanthosomus are yellowish linnvu tliiiuiiilumt, 

 the fins scarcely darker. Twenty-two specimens were all taken in the reef at Apia in compan\- with 

 Pseuilogiihiodoii rilrititui, which they much resemble in color. 



Gobias iixiilei is a species of Pamr/ohiodon closely resembling the jiresent species. 



ZONOGOBIUS Bleeker. 

 Zonogobius Bleeker, .A-rch. Neerl. 1875, 823 (semijasdalus=seinidolwlus. )

 nape and whole head naked, the head large, and the mouth almost vertictil. Tongue pointed: pecto- 

 ral without silk-like rays; teeth moderate; preopercle with a slight fringe of papilla'.

Huahinc; East Indies.
