224 THE SPONGES OF THE WEST-CENTRAL PACIFIC 



with oscules strewn over the exterior surface. S. kctostca de Laubenfels 1950 

 from Bermuda contains large oxea, small euasters, and (notably) contains 

 streptasters. It was incrusting. 



The species Stellettinopsis isis may be compared to Melophlus sarasin- 

 orum Thiele, 1899, page 8. This sponge from the East Indies is described 

 briefly. It has spicules a good deal like those of isis. It was a small lumpy 

 sponge. It is conceivable that a juvenile isis might be like this, but most of the 

 characteristics upon which the species isis is based are not mentioned by 

 Thiele. The genus Melophlus should be dropped in synonymy to the genus 

 Stellettinopsis. 



Bro'ndsted, 1934, page 8, records a sponge from the East Indies as 

 Jaspis bandae, new species. His description shows plainly that it is not a 

 J as pis but is a Stellettinopsis, and it should now be transferred to that genus. 

 It shows some relationship to the species isis, but was stony hard where isis 

 is woody, and it had no cloaca, where the cloaca of isis is conspicuous and 

 peculiarly set off. The asters of bandae were tylasters, where those of isis 

 are oxyasters. Bro'ndsted regarded the numerous 1 to 2 mm diameter openings 

 as oscules, whereas they are the pores. He thought that he found microscopic 

 pores in the solid cortical structures between the openings. Some of the sur- 

 face openings of his specimens doubtless really were oscules, however, 

 because if there be inhaling, there must also be exhaling. The species bandae 

 probably (but not yet certainly) should be dropped in synonymy to sarasin- 

 orum. 



The name selected for this species is that of an Ancient Egyptian 

 goddess. It is not descriptive but has been selected because of the imposing 

 appearance of the sponge. 



GENUS JASPIS Gray 

 Jaspis tuberculata (Carter) de Laubenfels 



Text Figure No. 154 



This species is here represented by the following: 

 U.S.N.M. No. 23003, My No. M. 382, collected July 11, 1949, by diver 

 (Jenira) at Likiep Atoll in the southeast corner of the lagoon near the 

 church. The depth was 3 meters, and the substrate was dead coral. Sev- 

 eral specimens of this species occurred in this vicinity. 



This species is also represented by a specimen collected at Bikini Atoll, 

 in the summer of 1948, by T. E. Bullock, his number C-72. 



This species is incrusting to massive, reaching a thickness of 2 or more 

 cm and a diameter of at least 6 cm. 



The exterior color in life was dark slaty gray, with a paler interior. The 

 specimen from Likiep had a yellowish drab endosome. Dr. Bullock describes
