156. ^Pecten albolineatus, Sby. Typical specimens of this 

 riiilippine Island shell. 



157. Pecten coeaxlinoides, D'Orb. One or two large specimens 

 showing beautiful coloration. Its headquarters are East Africa. 



158. Pecten pkicatus, Eeeve. 



159. Pecten histeionicus, Gmel. Panges from Singapore both 

 east and west. Our specimens are very finely coloured and perfect. 



160. Pecten in^quivalyis, Sby. A curious and rare form, the 

 valves, as the name implies, being very unequal. Quite typical : three 

 or four examples. 



161. Pecteist lENTiGiifosus, Peeve. Our specimens agree with 

 Eeeve' s description and figure ; it is a Philippine Island form. 



162. PECTEisr PALLIUM, L. This species seems to have a very wide 

 range throughout the tropical portion of the Eastern hemisphere. 



163. Pecteist testudineus, Reeve (PI. Ill, Eig. 4). A lovely 

 example, larger than the type in the British Museum, and measuring 

 30 X 25 mm. As illustrative of the danger in. describing small 

 Pectens, we may point out that the recently published ^ P. Thomaai, 

 Sby., appears to be the adult form of the species of which smaller 

 specimens were described as P. corneus, Sby. (1842), and P. nataiis, 

 Phil. (1845). 



164. PECTEif (Yola) pyxidatus, Born. Only small specimens, but 

 unmistakable. 



165. Plicatula imbeicata, Mke. 



166. Lima (Mantellum) aecuata, Sby. Young examples, agreeing 

 better with this than with any other known. sj)ecies. 



167. Mytilicardia distorta. Peeve. Headquarters in the Red Sea. 

 It seems nearly allied to M. excavata, Desh., from Australia. 



168. Mytilicardia yariegata, Brug. "We have received also 

 specimens from Mr. Townsend, from Karachi and the Mekran coast. 



169. Lazaria pica, Reeve. Apparently a variety of this species, 

 which is recorded from the Philippine Islands. 



170. IsocARDiA VULGARIS, Rceve. With headquarters in China, the 

 range of the section Meiocardla extends in a south-westerly direction. 



171. LuciNA (Codakia) exasperata. Reeve. One perfect example. 

 It is reported also from Honduras and Nicaragua, but this seems 

 doubtful. 



172. LuciNA (Codakia) Semperiana, Issel (PI. Ill, Eig. 1). One 

 specimen in fine condition, measuring 11 X 10"5 mm. 



173. Tellina (Tellia^ella) hippopoidea, Jonas {= T. striatula, Sby.). 

 Common.
