Mr. C. J, Galiuii on Longicorn Guleoptera. 19 



Attached to the exterior of several shells were some curious 

 dull green objects resembling fronds of" Fucus. These con- 

 sisted of a thallus-like expansion firmly adherent to the 

 shell, ending in a free vesicle, the contents of wiiich resemble 

 jolk of egg ] they are perhaps eggs of some fish. 



Family Mytilidse. 



10. Modiola, sp. 



An almost characteristic inhabitant of the mud of the Bay 

 of Bengal, as at present explored, in and near 100 fathoms, 

 is a species of Modiola with a very thin, transparent, polished 

 shell of an olive or dull yellow colour. The byssus is a large 

 bunch of fine silky threads saturated with fine mud usually. 

 Met with in beds in thick mud in 89 to 93 fathoms, and on 

 sand in 98 to 102 fathoms.

[Continued from vol. vi. p. 2G1.] 



Since the first part of these notes was written Professor Clir. 

 Aurivillius, of Stockholm, has called my attention to two 

 species belonging to the group, which were described by 

 Dalman in Schonherr's ' Synonymia,' and which have 

 apparently been omitted from the Catalogue of Gemminger 

 and Harold. The lirst species — Lamia serricornis — is con- 

 sidered by Prof. Aurivillius to be identical with Frosphilus 

 pilosicollis^ Thoms. ; and with this conclusion I quite agree. 

 The synonymy of the species will accordingly read : — 



Prosphilus serricornis, Dalm. 



^ Lamia serricornis, Dalm. Schcinh. Synon. i. '3, Appendix, p. IGO. 

 = Prosphihis inlosicollis, Thom3. 



Prof. Aurivillius was good enough to send me for examina- 

 tion some specimens of the second species mentioned above — 

 Lamia umbrinaj Dalm. Tlicse were found to agree quite well
