colony of Brachidontes pharaonis (P.
Fischer, 1870) (Bivalvia: Mytilidae) in Maltese waters (Central Mediterranean).
Triton, 20: 20-22.
The Lessepsian mytilid bivalve Brachidontes pharaonis (P. Fischer,
1870) is reported herein to have reached and established a small colony in
Maltese waters.
02. Cilia, D. P., 2009. On the presence of the alien freshwater
gastropod Ferrissia fragilis (Tryon,
1863) (Gastropoda: Planorbidae) in the Maltese Islands (Central Mediterranean).
Bollettino Malacologico, 45 (2): 123-127.
An established population of the
North-American freshwater gastropod Ferrissia
fragilis (Tryon, 1863) is recorded from the island of Malta (Central
Mediterranean) for the first time. This population was found in an
anthropogenic habitat at the northeast of Malta. Ferrissia fragilis is an invader of several freshwater habitats
throughout Europe and beyond. If released into the wild, it could present
competition for threatened Maltese freshwater Mollusca.
03. Cilia, D. P., 2010. A
student’s guide to the geology of the Maltese Islands. Unpublished B. Ed.
(Hons) dissertation, University of Malta, 228 pp.
The lack of geological education and
related literature in the Maltese Islands has meant that a large number of
resources, in the field and in theory, are not being exploited to the full by
Maltese students. A guide to the geology of the Maltese Islands was presented
to a number of students (five) and final-year science student teachers (nine) in
an attempt to gauge its motivational value and effectiveness. This guide was
built on a constructivist pedagogy to allow the student to develop and proceed
at one’s own pace. Evaluation by the students and the student teachers was
positive and most criteria for a constructivist method could be assessed. Most
respondents said that motivation indeed existed, but there were few accessible
resources to back up this interest. Geological education, if introduced, could
be incorporated into the current plans for a Co-ordinated Science syllabus. In
addition to cognitive skills geology has been seen to enhance the affective
attitudes towards the environment as well as increase scientific literacy
through psychomotor skills.
04. Cilia, D. P., 2010. A new species of Chloritis Beck, 1837 (Pulmonata: Camaenidae) from Sulawesi,
Indonesia. Visaya, 3 (1): 69-72.
The camaenid pulmonate Chloritis johannisi n. sp. is described
from the island of Peleng, Sulawesi, Indonesia, by means of conchological
characteristics. It can be distinguished from the sympatric congener Chloritis gruneri by the presence of
periostracal hair and from the similar Chloritis
talabensis by size, colour, hair density and whorl number.
05. Cilia, D. P., 2010. A note on shells of Pseudotachea splendida (Draparnaud, 1801) in the Maltese Islands
(Central Mediterranean). Triton, 22:
33-34.
Shells of the western European helicid Pseudotachea splendida (Draparnaud,
1801) are recorded from a plant nursery in Malta.
06. Cilia, D. P., 2012. A new Javan species of Agaronia Gray, 1839 (Neogastropoda,
Olividae). Novapex, 13 (1): 33-36.
A new species of olivid neogastropod from
West Java, Agaronia johnabbasi sp.
nov., is described according to conchological characters. It is distinguished
from congeners by means of its distinctive morphology and colouration.
