no. 3636 PARAPERCIS-SCHULTZ 11 



Parapercis xanthozona has 6 small brown spots in a row across top 

 of head behind eyes with a pair of small brown spots in front of the 

 row behind interorbital space, whereas P. somaliensis has 6 large spots 

 in a row across top of head behind eyes with the 2 spots at middorsal 

 line greatly enlarged and no spots in front of the enlarged ones; the 

 large dark spot just above the opercle in P. xanthozona is lacking in 

 P. somaliensis or confined to a very intense and small black spot sur- 

 rounding 2 pores. The series of dark spots on middle rays of caudal 

 fin with a light unpigmented streak separating the spots in P. xantho- 

 zona are lacking in P. somaliensis. Parapercis somaliensis has a shorter 

 snout and larger eye than P. xanthozona so that the preorbital is 

 contained in the eye of P. somaliensis 1.8 to 2.1 instead of 1.1 to 1.4 

 in P. xanthozona; the preorbital into the postorbital is 1.5 to 1.8 instead 

 of 1.9 to 2.2; the snout in head is 3.1 to 3.2 instead of 2.6 to 2.8, 

 respectively. 



The name "somaliensis" refers to the Republic of Somali off the 

 shores of which this new species was collected.
