CINGULOGOBIUS 201 



The Bureau of Science collection contains one specimen from 

 Puerto Princesa, Palawan, and one from Sitankai, 18 and 19 

 millimeters long, respectively. 



Mr. Scale obtained this species from Samal Island, Davao 

 Gulf, and it was recorded by Jordan and Seale from southern 

 Negros ; Weber obtained it also at Sanguisiapo, an island of the 

 Tawitawi group, Sulu Province. 



This uniquely marked and easily recognized goby is found on 

 coral reefs from the Red Sea eastward throughout the East 

 Indies, and southeast in the Pacific Ocean to the Samoan and 

 Tonga Islands. 



Genus 39. CINGULOGOBIUS g. nov. 



This genus is very close to Zonogobius, from which it may be 

 at once distinguished by the nape being scaled instead of naked.

 forward to eyes, their teeth visible only with a compound micro- 

 scope; the scales on sides of nape reduced in size; a few small 

 scales on upper part of opercle, the cheeks naked; fine scales 

 on breast and base of pectoral; the mouth large, oblique, with 

 three rows of teeth in upper jaw, two rows in lower, the outer 

 row in each enlarged and widely spaced, but without canines; 

 the tip of tongue free, subtruncate; the dorsals separate, the 

 first dorsal lower than second ; the caudal rounded, shorter than 

 head; no free silklike rays on upper part of pectoral. 



Dorsal VI, 1-10 to 12; anal I, 9 to 11; gill openings wide, 

 extended forward, isthmus narrow; branchiostegals 4. Generic 

 type, Pleurogobius boulengeri Seale.
