The fauna of deepsea cirripede barnacles of equa
torial zone of the eastern Pacific Ocean shows great
biological diversity. It has been studied since the late
19th century; among large expeditions of that time
that worked in this area there were expeditions aboard
(1873–1876, Great Britain),
(1893–1906, United States) and
1900, Netherlands). Among the expeditions of the
early 20th century, let us mention the Dr. Mortensen’s
Expedition (1914–1916, Denmark). The results of
studies of cirripedes that were found during these
expeditions were published in several papers [7, 13–
16, 19, 20]. Among comparatively recent publications
on cirripede barnacles from this area, it is pertinent to
mention the studies performed in the late 20th cen
tury, within the framework of the MUSORSTOM
project [25–27] and the results of an expedition of Tai
wanese scientists to the Philippines .
The deepsea fauna of equatorial zone of the east
ern Pacific was studied in the Soviet Union and still
attracts the attention of Russian scientists. One of
these expeditions was the ninth cruise of the R/V
. To date, the materials on cir
ripedes collected during this cruise have been partially
treated. For example, one new species of barnacle was
described by Zevina . However, some samples have
never been examined thus far. This paper provides the
results of the treatment of earlier nonexamined col
lections of cirripede barnacles that were collected dur
ing the expedition.
MATERIALS AND METHODS
The material was collected during the ninth cruise
Akademik Mstislav Keldysh
of the Institute of
Oceanology, Academy of Sciences of USSR
Russian Academy of Sciences). The samples were
fixed in 4% formalin and then transferred into 70%
ethanol. The material is deposited in the collections of
the Institute of Oceanology RAS and was kindly
loaned to the author for examination.

—Previously unidentified barnacles (Cirripedia: Thoracica) that were collected during the ninth
cruise of the R/V
Akademik Mstislav Keldysh
in the equatorial zone of the East Pacific Ocean from depths of
1422–1490 m are examined. The following species were found in two samples we studied:
Annandaleum gruvelii gruvelii
. These species are described, illustrated, and compared to the published data.
This study extends the previously known areas of distribution of some species and adds further data on their
