564 MESSRS. E. HEEON-ALLEN AND A. EAELAND ON THE 



9 Stations. 



Generally distributed, frequent at a few Stus. and very common at Stn. 11. The 

 specimens throughout are generally identical with Brady's figure, but at Stn. 11 there 

 is a considerable amount of variation. The majority of the specimens are of the short 

 regularly tricarinate type, but here, and at Stn. ] B, a few specimens of a very elongate 

 type were found. Brady recorded the species from Madagascar and Algoa Bay, and 

 Millett as " very rare " in the Malay Seas. It occurs rarely in dredgings from 

 Cebu, Philippine Islands, 45 and 120 fathoms, and is probably of wide distribution 

 in tropical shallow seas.

Universally distributed and often abundant. In Brady's original figure and in the 

 subsequent authorities {supra) the early chambers are shown as vertical or but slightly 

 oblique. In the Kerimba specimens a complete series can be obtained at many Stns. 

 in which the early chambers range from vertical to very oblique [as in M. hosciana 

 (d'Orbigny)]. Wiesner (W. 1912, AM. pp. 220-222, fig. 2) has separated the 

 Malay specimens of M. hosciana (d'Orb.), figured by Millett, under the new specific 

 name 3f. milletti on account of " the narrow build, the strongly-marked oblique setting 

 of the middle chambers, the large aperture with prominent lip, the frequently produced 

 aperture-neck, the deeper sutures, its slighter polish, and the greater inclination to 

 build cornered and keeled varieties." He has further separated under the varietal 

 name of M. milletti, var. carinata, keeled specimens identical with the series found at 

 Kerimba, and which appear to us to agree in all essential characteristics, except the 

 oblique setting of the chambers, with Brady's M. cultrata. In view of the complete 

 range of variations in the axis of the early chambers, it does not seem to us possible 

 or desirable to diff'erentiate between Wiesner's varieties and Brady's type, and we 

 have therefore dealt with the whole group under the above heading. 



At nearly all the Stns. where the species occurs, decorated varieties are abundant, 

 ranging between specimens feebly sulcate at the aboral extremity to specimens strongly 

 sulcate all over. These latter represent Wiesner's variety M. milletti, var. carinata- 

 striata, with specimens of which he has been so courteous as to supply us.
