ASPEKGILLUM.— Plate I. 



another section. 3. A. Javanum, pulchrum, and radix 

 (Aspergillum, PeniciHus, and Clepsidra, Gray), in which 

 the sheath is attenuated, and is closed in at the bottom 

 by an elaborately perforated disc, with a more or less 

 densely branched, finely tubed frill. 4. A. tuberculatum 

 and clavatum (Argtene, Gray), in which the sheath is 

 slender, agglutinating sand and fine pebbles, and is closed 

 at the bottom by a disc of small size, only lightly promis- 

 cuously perforated, encircled by a regular well developed 

 frill of a characteristic sloping growth ; the valves of this 

 type have the shelly wall of the sheath projected over them 

 in a peculiar biforked manner. 5. A. agglutinans and 

 Philippinense (Foegia, Gray), in which the tube is club- 

 shaped, densely agglutinated with sand, pebbles, and shell- 

 debris, and is contracted below the disc, taking the form 

 of a small clump of short, wider tubes. 6. A. Strangei 

 i Eumphreyia, Gray), the adherent species already de- 

 scribed, of which Dr. Gray constitutes a separate subfamily. 

 All the Aspergilla belong to the Eastern Hemisphere. 

 A. vaginiferum iuhabits the Red Sea, A. Javanum and its 

 allies inhabit the eastern seas, about the Philippine Islands, 

 Java, Ceylon, and Singapore, and the more distorted forms 

 are from Australia and New Zealand. 



Species 1. (Fig. a, b, Mus. Cumiug.) 



Aspergillus annulosum. Asp. testa valvis sublate 

 ovatis, tumidiusculis ; vagina ehngato-altenuaid, un- 

 dique undato-annulosd; fimbria perampld, regidari, tu- 

 bulin longis, minimis, confer/is; disco valde convexo, 

 perforationibus parvis, numerosis, parum lubulosis. 



The kinged Aspergillus. Shell with the valves ra- 

 ther broadly ovate, somewhat swollen ; sheath elon- 

 gately attenuated, wave-ringed throughout ; frill very 

 large, regular, tubes long, very small, close-set ; disc 

 very convex, with the perforations small, numerous, 

 and but little tubular.

Hab. Singapore. 



The little valves of this species are smaller in propor- 

 tion to those of its nearest ally, A. Javanum, and they are 

 more swollen, short and broad. The fringe is composed 

 of a remarkably close-set row of slender tubes, very re- 

 gular in their development, as shown at Fig. 1 b. The 

 conspicuous ringed growth of the sheath of the shell is 

 the feature after which the species is named. 



ovatis, concentrice tenuissime lirato-striatis, poslice an- 

 gulaiis ; vagina longissimd, subrectd, arenulas aggluti- 

 nanle, limbo ad superam extremitatem conspicue trifa- 

 riam ad quinquefariam foliato ; fimbria brevi, tubulis 

 subamplis, liberis, sape irregularibus ; disco convexo, 

 amplo, perforationibus amplis, tumidiusculis. 



The sheath-bearing Aspergillus. Shell with the 

 valves oblong-ovate, concentrically very finely ridge- 

 striated, posteriorly angled ; sheath very long, nearly 

 straight, agglutinating grains of sand, with the edge 

 of the upper extremity conspicuously foliated ; frill 

 short, with the tubes rather large, free, and often ir- 

 regular ; disc convex, large, with the perforations 

 large, and rather swollen.

 TJ'amea vaginifera, Gray. 



Hab. Red Sea. 



This fine species, of which A. Delessertianum is pro- 

 bably a variety, by much the largest of the genus, is dis- 

 tinguished from all others by the treble and sometimes 

 quintuple foliation of the upper extremity of the sheath. 

 The valves are of an oblong form, showing five concentric 

 lilies of growth, and are distinctly angled posteriorly. 



Species 2. (Mus. Cuming.) 

 Aspergillus vaginieeru.m. Asp. testa valvis oblongo- 



Species 3. (Mus. Cuming.) 



Aspergillus Javanum. Asp. testa valvis sub/ate ovatis, 

 tumidiusculis ; vagina elongato-attenuatd, subannulosd ; 

 fimbria ampld, irregulari, subfiexuosd, tubulis parvis, 

 luugis, confertis, hie illic ramoso-agglomeraiis ; disco 

 valde convexo, perforationibus numerosis, parvis, pa- 

 rum tubulosis. 



The Java Aspergillum. Shell with the valves rather 

 broadly ovate, somewhat swollen ; sheath elongately 

 attenuated, faintly ringed ; frill large, irregular, rather 

 flexuous, tubes small, long, close-set, here and there 

 ramosely agglomerated ; disc very convex, perfora- 

 tions numerous, small, but little tubular.

 Aspergillum Listeri, Gray. 

 PeniciHus Javanus, Bruguiere. 

 Brechites Javanus, Adams. 

 Aspergillum sparsum, Sowerby. 



Hab. Java. 



The sheath of this species presents very obvious indica- 

 tions of the ringed growth of A. annulosum. The frill is 

 more irregular, the tubes inclining, agglomerate here and 

 there in branching tufts.
