59. TRisERiATA. (pi. xlv. f. 119.) Gray, 1. c. p. 61. 



Testa gracillime subulata, turrita, pallide flava ; anfractibus 

 numerosissimis, circa viginti-novem, planulatis, superne 

 seriel)us duabus tuberculorum rotundorum cinctis, infra 

 cancellatis, ultimo quadrate ; apertura perparva, quadrata ; 

 columella antice producta ; canali mediocri. 



Of greater length, compared with the diameter, than any 

 other species ; and it is very elegantly proportioned. The 

 whorls are furnished above with two series of rounded tuber- 

 cles, and between which the girdling line passes. Our speci- 

 mens are of a pale yellow varying to a browner colour. 



Island of Ticao, Philippines ; six fathoms, sand : Cuming. 

 China Sea ; twenty-two fathoms. 



The characters presented by this and the two preceding 

 species are aberrant from the more typical Terebra, and pre- 

 sent the only safe grounds on which, at present, any sectional 

 division can be attempted. As such, I have for some time 

 regarded it, and also assigned the group the following desig- 

 nation, and as my views as to its value seem fixed, it is here 

 introduced. 



SUBGENUS, MYURELLA. 



Testa longissime subulata ; anfractus numerosissimi, 

 superne cingulo tuberculoso instruct!, inferne transversim 

 exculpti, vel rarius totius leeves. Apertura perparva, canali- 

 culata. Columella antice producta. 



I do not doubt that several other species might be placed 

 here with advantage, but I refrain from doing so now, as 

 between the two, there appears to be a gap which the speci- 

 mens before me do not enable me to fill up, and also because 

 these are often not in such a condition as to unable me to 

 decide. Thus, I regard the production of the columella 

 forward as an inner lip as indispensable, but this character in 

 many cases beforeus is not developed, since it is always 

 attendant on mature age. 



60. LAEVIGATA, (pi. xliv. f. 93.) Gray, 1. c. p. 61. 



Testa longissime subulata, acuminata, turrita, concolore ; 

 anfractibus numerosis, planulatis, superne sulco divisis, inferne 

 iineis parvis impressis transversim instructis ; area superiore 

 laevi, integra ; apertura parva, subquadrata ; columella con- 

 torta, acuta ; canali mediocri. 



T. funiculata approaches the present species very closely,
