1861.] M. o. A. L. morch's review of the VERMETID^. 1/7 



Spira turritelloidea, Candida, anfr. plants confusis, triliratis, lira 

 mediana valida compressa acuta. 



Bab. Ins. Philippin. (H. Cuming). 



A specimen affixed to the tube of a Rocellaria (J) . The sutures 

 of the spire are very difficult to distinguish ; it looks as if the two 

 equal lirse between the two carinse weie situated on one and the 

 same whorl. 



?Var. a. LiTUiNA. 



T. irregulariter planorbiformis, anfr. latere affixo piano per totam 

 longitudinem ; latere libera tereti, Kris inccqualibus planis, lira 

 peripherica lata ; latere interna liris canfertis, interstitiis lirula 

 intercalaiite ; rugce incrementi irregulures, appraximatce ; anfr. 

 ultimus flavus, strigis canfertis confluentibus lividis ; apertura or- 

 bicularis, subangulata. 

 Diam. 12-14 m. 



Hab. Ins. Philippin. (/?. Cuming). 



A detached specimen, showing the cast of the denudated layers 

 of a pearl-oyster, and exhibiting a feeble pearly lustre. Spire typi- 

 cal. I have found two specimens with about three detached whorls 

 in a mass oi Petaloconchus flavescens. Carp., said to*be from Sicily ; 

 they only differ in the colour being of a dull white, and not glossy 

 white as in the two forms described. 



36. Vermiculus pellxjcidtjs, Brod. & Sow., 1829. (PI. XXV. 

 figs. 17-20.) 



T. pellucida, longitudinaliter striata, apicem versus carinata. 



The striae, which become carinated towards the apex, are best seen 

 in the young shell. The species in texture has somewhat the ap- 

 pearance of Magilus, Sow. & Brodr. 



Vermetus pellucidus, Brodr. & Sow. Zool. Journ. iv. p. 369. 



Var. a..PLANORBOIDES. 



Serpula regularis, Chenu, 111. t. 10. f. 14. 



T. tenuiuscula, irregulariter planorbiformis, lateraliter affixa ; anfr. 

 longitudinaliter pulcherrime dense striati et plano-lirati, lircB in 

 anfr. primis fortiores, latere interna plana ; apertura obliqua 

 orbicularis, latere interna affixa. 

 Diam. 9 m. 



Spira turritelloidea, anfr. vix convexiusculi, carina valida com- 

 pressa acuta submediana, supernejuxta suiuram lira prominula et 

 inferne lirula suturali in anfr. primis minutissima. 

 A specimen without locality in Mr. Cuming's collection, a little 

 smaller than the quoted representation ; the affixed side shows some 

 agglutinated shell-rudiments, and two or three flat marks, very hkely, 

 from the lustre, those of a Margaritifera. 



Var. aa. LAauEARis. 



T. ut iupracedente, sed anfractus connati teretiusculi ; anfr. ultimus
