The Zebu Aspergillum. Shell with the valves oblong- 

 ovate, posteriorly rather expanded ; sheath aggluti- 

 nating grains of sand, slightly attenuated at the upper 

 part, longitudinally grooved on each side, abruptly 

 contracted at the lower ; frill rather irregular, tubes 

 distinct, free ; disc small, perforations very few, tu- 

 bular.

Hab. San Nicolas, Island of Zebu, Philippines. 



An interesting, well-marked species, in which the disc 

 is contracted to an area with frequently only four perfora- 

 tions, while the tubes of the frill are also few in number 

 and free. 



Species 9. (Mus. Cuming.) 



Aspergillum dichotomum. Asp. testa, valvis oblongo- 

 ovatis, subtrapezoideis; vagina breviusculd, superne gra- 

 dutim atleuuatd, savpe distortd, inferne subcontract a ; 

 fimbria subampld, valde irregulari, tubulis tenuibus elon- 

 gates promiscue didortis ei agglomerates, stepe dichoto- 

 mis ; disco paroiusculo, convexo, minute per forato. 



The dichotomous Aspergillum. Shell with the valves 

 oblong-ovate, somewhat trapezoid ; sheath rather 

 short, gradually attenuated towards the upper part, 

 often distorted, slightly contracted at the lower; frill 

 rather large, very irregular, with the tubes elongated, 

 promiscuously distorted and agglomerated, often di- 

 chotomous ; disc rather small, convex, minutely per- 

 forated.

Hab. Singapore. 



This species, collected in great plenty by Mr. Cuming, 

 at Singapore, has a most irregular frizzly frill, with the 

 tubes dichotomously branched or forked.

The Philippine Aspergillum. Shell with the valves 

 rather oblong-ovate, somewhat expanded posteriorly ; 

 sheath agglutinating grains of sand, rather attenuated, 

 and grooved on both sides at the upper part, abruptly 

 contracted at the lower; frill irregular, with the tubes 

 elongately distorted and free ; disc small, perforations 

 very few, tubular. 



Chenu, Illus. Conch. Asp. p. 3. pi. 4. f. 7, 7 a. 



This, I fear, is only a variety of A. Zebuense, in which 

 the frill is more irregular, with the tubes rudely and vari- 

 ously distorted.

Species 11. (Mus. Cuming.) 



Aspergillum radix. Asp. testa valvis ovatis, utrinque 

 subangulatis ; vagina superne compressd et longitudi- 

 naliter sulcata, inferne globoso-tumidd, delude anguste 

 contractu ; fimbria ampld, tubulis elongatis, confertis, 

 paruni irregularibus ; disco parvo, profuse minute per- 

 forata. 



The root Aspergillum. Shell with the valves ovate, 

 slightly angled at each end ; sheath compressed, and 

 longitudinally grooved at the upper part, globosely 

 swollen, and then narrowly contracted at the lower ; 

 frill large, with the tubes elongated, crowded, but 

 little irregular ; disc small, profusely minutely per- 

 forated.

 Penicillus radix, Gray. 



Hab. Amboyna. 



A species of elegant and very characteristic growth, but 

 more specimens are needed to show that the distinguish- 

 ing characters are permanent. Mr. Cuming has three 

 specimens all exactly alike. 



Species 12. (Mus. Cuming.) 



Aspergillum disjunctum. Asp. testa valvis late ovatis, 

 parviusculis ; vagina superne attenuatd, inferne tumidi- 



usculd, delude subcontractd ; fimbria ampld, valde irre- 

 gulari, tubulis longissimis, hie it/ic valde extends et
