the shell, which is further characterized by having the interstices of the ribs sculptured with 

 spiral equidistant ridges. 



40. CHEMNITZIA, D'Orbigny. 



1. Chemnitzia gbandis. PI. XI. Kg. 17. Chemn. testa elongato-turrita, anfractibus compluribus, 

 plano-convexis, suturis tamen distinctis, longitudinaliter creberrime costatis, costis subprominentibus, 

 flexuosis, anfractu ultimo infra lsevigato ; alba. 



Hab. Eastern Seas. 



The ribbed sculpture of the whorls ceases at the sutures ; below that point the whorls 

 are smooth, as shown in the last whorl. 



41. EULIMA, Bisso. 



The head of Eulima is small, with the tentacles subulate, and close together at the base, 

 where they are rather swollen. The eyes are situated at the back of the head, behind the 

 tentacles. The foot is rather expanded, especially at the sides, and is furnished with an ovate 

 sub-spiral operculum. The polish of the shell is occasioned by the front edge of the mantle 

 being extended over it ; the lobes are, however, difficult to observe, in consequence of the 

 extreme timidity of the animal in speedily retracting them, when disturbed. 



The soft parts of Eulima major are, like the shell, of which several fine specimens were 

 collected, of an opake pearly white, except that the tentacles are delicately tinged with orange 

 in the middle and with yellow at the tip. The eyes, which are black, are usually concealed 

 beneath the front of the shell. 



1. Eulima unilineata. PL XL Pig. 23. Eul. testa aciculata, anfractibus octo, plano-contiguis, 

 apertura suboblonga ; rufo-brunnea, linea unica nigricante cingulata. 



Hab. Sooloo Sea. 



A rich red-brown sharply aciculated shell, with the sutures almost obsolete, encircled

2. Eulima bilineata. PI. XL Pig. 24. Eul. testa aciculata, anfractibus novem ad decern, plano- 

 convexis, apertura oblonga, labro superne inflexo ; pellucido-alba, vitrea, lineis tenuibus duabus castaneis 

 cingulata. 



Hab. Sooloo Sea (from the stomach of an EcJdnus). 

 A light transparent glassy shell, encircled with two delicate brown lines, of which the lower 

 falls exactly in the place of the sutures. 



3. Eulima Mindoeoensis. PI. XL Pig. 25. Eul. testa elongato-turrita, basi subobesa, suturis im- 

 pressis, anfractibus decern, convexis, apertura ovata ; pellucido-alba, opaco-albo maculata. et lineata.
